Using fgets to read from the keyboard
Getting numbers from strings
• Once we've got a string with a number in it (either from a file or from the user typing) we can use atoi or atof to convert it to a number • The functions are part of stdlib.h
File handling in C
• In C we use FILE * to represent a pointer to a file. • fopen is used to open a file. It returns the special value NULL to indicate that it couldn't open the file.
FILE *fptr; char readfname[1000]; fgets (readfname,1000,stdin); fptr= fopen (readfname,"w"); /* oopsie - file name also has \n */
Even experienced programmers can make this error
char numberstring[]= "3.14"; int i; double pi; pi= atof (numberstring); i= atoi ("12"); Both of these functions return 0 if they have a problem

Models of Software Systems Fall 2004ObjectivesScientific foundations for software engineering depend on the use of precise, abstract models and logics for characterizing and reasoning about properties of software systems. There are a number of basic models and logics that over time have proven to be particularly important and pervasive in the study of software systems. This course is concerned with that body of knowledge. It considers many of the standard models for representing sequential and concurrent systems, such as state machines, algebras and traces. It shows how different logics can be used to specify properties of software systems, such as functional correctness, deadlock freedom, and internal consistency. Concepts such as composition mechanisms, abstraction relations, invariants, non-determinism, and inductive and denotational descriptions are recurrent themes throughout the course.By the end of the course you should be able to understand the strengths and weaknesses of certain models and logics, including state machines, algebraic and trace models, and temporal logics. You should be able to apply this understanding to select and describeabstract formal models for certain classes of systems. Further, you should be able to reason formally about the elementary properties of modeled systems.OrganizationLectures. Classes meet Monday & Wednesday, 5:30-6:50 am, in Newell-Simon 1305.Communication. We will be using the CMU Blackboard System this year for distributing most course materials, providing a general course bulletin board, and keeping track of student email addresses. In addition you can useOffice Hours: The instructor and the TAs have weekly office hours, listed above. We are also available other times by appointment.1.Email: We welcome email about the course at any time.2.Readings. Most lectures will have a reading assignment that we expect you to complete before you come to class. There is one required textbook for the course: Concurrency: State Models and Java Programs, by Magee and Kramer [MK99]. In addition, there is an optional companion text Using Z: Specification, Refinement, and Proof, by Woodcock and Davies [WD96]. This text is available on-line at /.An optional reference book may also be useful: The Z Notation: A Reference Manual, Second Edition, by J. M. Spivey (available on the web through /~mike/zrm). Some readings are in the form of handouts to supplement lectures; other additional readings are technical papers. These will be made available as needed throughout the course. Finally, for supplementary detail, there are a number of books noted in the References section at the end of this document.Homework Assignments. The course is organized around (roughly) weekly homework assignments and a set of three projects. The purpose of the assignments and projects is to give you practice in using the models, logics, and tools of the course. We encourage you to discuss your homework with other students, but the final write-up must be your own work.To give you the most opportunities to learn from the homework assignments, we will allow you to redo problems that didn't receive a passing grade. A redone homework must be turned in at the class following the one on which it is handed back. Problems done correctly the first time will be given more weight in the final grade.Projects. We will be assigning three group projects that are designed to give you a chance to apply the ideas of the course tosemi-realistic case studies. Each project will be completed by a team. Team members are expected to participate equally in the projects.We will distribute a team peer evaluation at the end of the semester.On-line materials. Most of the course materials will be available electronically via the CMU Blackboard System(/blackboard/). You will find copies of the lecture slides, handouts, homework, and readings. It will be your responsibility to make copies of these to bring to class or to use for homework.Some of the course materials have web sites. These are:Using Z: /Concurrency: State Models and Java Programs: /concurrency/The Z Notation: /~mike/zrm/PhD Option. Students taking the course for PhD credit students will be required to complete a course project. This project is described in separate handout.Exams. There will be a (take-home) mid-term (handed out Wednesday, October 20, due back Friday, October 22 by 5:00 p.m.) and a formal (in-class) final examination. Both exams will be open-book.Grading. The course grade will be determined as a combination of five factors: homework assignments (30%), projects (30%), midterm exam (15%), and final exam (25%). Final grades may be adjusted based on instructors judgment.Bold refers to Using Z [WD96].*Marks classes that follow a holiday.。

讲座英文推荐作文范文英文回答:In the realm of public speaking, lectures stand as a formidable and influential form of discourse. They offer a platform for experts and thought leaders to share their insights, research findings, or perspectives on a given topic with an audience. As such, they play a pivotal role in the dissemination of knowledge, the stimulation of intellectual discourse, and the shaping of societal understanding.The effectiveness of a lecture hinges on several key elements, including the speaker's mastery of the subject matter, their ability to articulate their ideas clearly and persuasively, and their capacity to captivate and engage the audience. A well-crafted lecture captivates listeners by drawing them into the speaker's world of ideas, leaving them informed, inspired, and eager to explore the subject further.In choosing a topic for a lecture, the speaker must consider the audience's interests, knowledge level, and the overall purpose of the event. The lecture's structure should be clear and logical, with an engaging introduction that grabs the audience's attention, a body that presents the main arguments and supporting evidence, and a conclusion that summarizes the key points and leaves a lasting impression.Effective delivery involves not only the speaker's verbal communication but also their non-verbal cues. Maintaining eye contact, using gestures appropriately, and modulating the voice can significantly enhance the audience's engagement and comprehension. Moreover, incorporating audio-visual aids, such as slides or videos, can further enhance the learning experience by providing visual representations of complex concepts and data.In recent years, the advent of online platforms has expanded the reach and accessibility of lectures. Webinars and virtual conferences allow speakers to connect withaudiences worldwide, breaking down geographical barriers and enabling knowledge sharing on a global scale. However, delivering an engaging and effective online lecture requires careful consideration of audience engagement techniques, such as interactive polls, Q&A sessions, and breakout rooms, to maintain active participation and foster a sense of community among attendees.Regardless of the format, the ultimate goal of alecture is to inform, inspire, and provoke thought. It is an opportunity for speakers to share their expertise, challenge assumptions, and encourage a deeper understanding of the world around us. Through the careful planning, engaging delivery, and thoughtful incorporation of audience-centered techniques, lectures continue to serve as a powerful vehicle for knowledge dissemination and intellectual growth.中文回答:一场成功的演讲由以下几个关键元素决定,演讲者对主题的掌握程度、清晰而有说服力地表达思想的能力,以及吸引观众并与之互动。

Luther’s Reform: Free Theology from Politics
路德的改革和体现这种改革的德意志各公国的革命,通过清除教会的 权能打破了教会法和世俗法这种罗马天主教的二元制。在路德主义获 得成功的地方,教会逐渐地被作为无形的、无政治意义的和无法律意 义的东西;仅有的主权和法律(政治意义上的)是世俗王国或公国的 主权和法律。事实上,刚好在此前,马基雅维里曾以一种新的方式使 用“国家”一词,用来表示纯粹的世俗社会秩序。路德教的改革者们 在一种意义上是马基雅维里派:他们对人能够创造反映永久法的人法 的权力这一点持怀疑态度,他们明确否认发展人法是教会的任务。这 种路德派的怀疑论使法律实证主义的法律理论的出现成为可能,它把 国家的法律视为在道德上中立的,是一种手段而不是目的,是一种表 现主权政策和确保服从它的办法。但法律的世俗化和实证主义法律理 论的出现只是路德宗教改革对西方法律传统贡献的一个方面。另一个 方面是同等重要的:通过使法律摆脱神学教条和基督教教会的直接影 响,这种宗教改革能够使法律经历一种新的和有前途的发展。用德国 伟大的法学家鲁道夫·索姆的话讲:“路德的改革不仅使对信仰的革新 而且也是对世界--宗教生活世界和法律世界--的革新”。 Berman

Using The Scientist@‘s Unit function makes the change in T∗ straight forward. In The Scientist@, Unit(+) = 1 and Unit(-) = 0, so defining T∗ = ( T – T iv ) ⋅ UNIT ( T – Ti v ) meets these needs. This equation is utilized in The Scientist@’s companion product PKAnalyst@ also by MicroMath. Since the route of administration is an infusion and we would know how much we gave (Dose), how fast we gave it (Q), and over how long the infusion lasted (Tiv), the only other variables in the equation are K and Vd.

The creditor, therefore … gives credit to that capital, gives credit to the company on the faith of the representation that the capital shall be applied only for the purposes of the business, and he has therefore a right to say that the corporation shall keep its capital and not return it to the shareholders, though it may be a right which he cannot enforce otherwise than on a winding up (Jessel MR)Trevor v Whitworth (1887) 12 App Cas 409: “One of the main objects of the legislature, in restricting the power of limited companies to reduce the amount of their capital as set forth in the memorandum, is to protect the interest of the outside public who may become their creditors. … Paid-up capital may be diminished or lost in the course of the company’s trading; that is a result which no legislation can prevent; but persons who deal with, and give credit to a limited company, naturally rely upon the fact that the company is trading with a certain amount of capital already paid … and they are entitled to assume that no part of the capital which has been paid into the coffers of the company has been subsequently paid out, except in the legitimate course of business.” (Lord Watson)Minimum share capitalS. 761S. 763(1) “The authorised minimum”, in relation to the nominal value of a public company’s allotted share capital is – (a) £50,000 or (b) the prescribed euro equivalent.”Issue for non-cash considerationS. 582(1) Shares allotted by a company, and any premium on them, may be paid up in money or money’s worth (including goodwill and know-how).Re Wragg Ltd [1897] 1 Ch 796:“Provided a limited company does so honestly and not colourably, and provided that it has not been so imposed upon as to be entitled to be relieved from its bargain … agreements by limited companies to pay for property or services in paid-up shares are valid and binding on the companies and their creditors.” (Lindley LJ)Salomon v A.

One must examine the commercial realities of the transaction and decide whether it can properly be described as the giving of financial assistance by the company, bearing in mind that the section is a penal one and should not be strained to cover transactions which are not fairly within it.” (Hoffman J)Anglo Petroleum Ltd v TFB Mortgages [2008] 1 BCLC 185“In cases where its application is doubtful, it is important to remember its central purpose, to examine the commercial realities and to bear in mind that it is a penal statute.” (Toulson LJ) S. 678(2) Subsection (1) does not prohibit a company from giving financial assistance for the acquisition of shares in it or its holding company if –(a) the company’s principal purpose in giving the assistance is not to give it for the purpose of any such acquisition, or(b) the giving of the assistance for that purpose is only an incidental part of some larger purpose of the company,and the assistance is given in good faith in the interests of the company.S. 678(4)Brady v Brady [1989] AC 755:“[The first exception] envisages a principal and, by implication, a subsidiary purpose. The inquiry here is whether the assistance given was principally in order to relieve the purchaser of shares in the company of his indebtedness resulting from the acquisition or whether it was principally for some other purpose – for instance, the acquisition from the purchaser of some asset which the company requires for its business. … That is not this case, for the purpose of the assistance here was simply and solely to reduce the indebtedness incurred by [the company].”“[The second exception] is where it is not suggested that the financial assistance was intended to achieve any other object than the reduction or discharge of the indebtedness but where that result (ie the reduction or discharge) is merely incidental to some larger purpose of the company. … What has to be sought is some larger overall corporate purpose in which the resultant reduction or discharge is merely incidental.”“[I]t is important to distinguish between a purpose and the reason why a purpose is formed. The ultimate reason for forming the purpose of financial the acquisition may, and in most cases probably will, be more important to those making the decision than the immediate transaction itself. But “larger” is not the same thing as “more important”, nor is “reason” the same as “purpose” … The purpose and the only purpose of the financial assistance is and remains that of enabling the shares to be acquired and the financial or commercial advantages flowing from the acquisition, whilst they may form the reason for forming the purpose of providing financial assistance, are a by-product of it rather than an independent purpose of which the assistance can properly be said to be an incident.” (Lord Oliver)Ss. 681 & 682: exceptions(i) lawful distribution of co’s assets by dividend or on winding-up;(ii) reduction of capital;(iii) allotment of bonus shares;(iv) redemption of shares;(v) purchase of shares;(vi) various reconstructions and arrangements under IA 1986(vii) loan of money in ordinary course of money-lending business if co is private co, or if public co provided that it does not reduce net assets or is provided out of distributable profits; (viii) employee share schemes.S. 680(1) : offenceHeald v O’Connor [1971] 1 WLR 487Re Hill and Tyler Ltd [2005] 1 BCLC 41Carney v Herbert [1985] AC 301Belmont Finance Corp v Williams Furniture Ltd (No. 2) [1980] 1 All ER 393 Wallersteiner v Moir [1974] 1 WLR 991Re Continental Assurance Co [1997] 1 BCLC 48。

Pointer Arithmetic 2
• A pointer is another type of array and we can mix between them in certain arrays • If we define an array we can use pointers to access it
Extern statement
• Only used with global variables in multi-file projects. • Says to compiler "don't worry, this is dealt with elsewhere"
file1.cpp
int glob_array[100];
Multi-file programming - how
• Create a "header file" (a file ending in .h) which contains all the prototypes, enums, #defines, structs, typedefs etc for your code • Create a number of C source code files - they should all #include your header file. • Source files NOT header files contain the functions. • One (and only one) of your C source code files contains main. • In VC++ you have to add source files to a workspace to get them to compile properly.

Rounding Off Probabilities
When expressing the value of a probability, either give the exact fraction or decimal or round off final decimal results to three significant digits. (Suggestion: When a probability is not a simple fraction such as 2/3 or 5/9, express it as a decimal so that the number can be better understood.)

Odds
The actual odds against event A occurring are the ratio P(A)/P(A), usually expressed in the form of a:b (or “a to b”), where a and b are integers having no common factors. The actual odds in favor of event A occurring are the ratio P(A)/P(A), which is the reciprocal of the actual odds against the event. If the odds against A are a:b, then the odds in favor of A are b:a. The payoff odds against event A occurring are the ratio of the net profit (if you win) to the amount bet. payoff odds against event A = (net profit) : (amount bet)
讲座计划的英文作文初一
讲座计划的英文作文初一Title: Planning a Lecture。
In our school, planning a lecture is a significant task, one that requires careful consideration and organization. Whether it's a guest speaker, a teacher's presentation, ora student-led seminar, the process involves various stepsto ensure its success.First and foremost, selecting a topic is crucial. The topic should be relevant, engaging, and align with the interests and needs of the audience. It could be related to academic subjects, current events, or even personal development themes. Once the topic is decided upon,thorough research is necessary to gather enough information and resources to deliver a comprehensive lecture.After determining the topic and conducting research,the next step is to outline the lecture. This involves structuring the content in a logical sequence, startingfrom an introduction to capture the audience's attention, followed by the main body where key points are elaborated upon, and concluding with a summary or call to action. The outline serves as a roadmap for the speaker, ensuring smooth transitions between different parts of the lecture.Visual aids play a crucial role in enhancing the effectiveness of a lecture. Whether it's PowerPoint slides, charts, graphs, or videos, visual elements help toreinforce key points, clarify complex concepts, and maintain the audience's interest. However, it's essential to use visual aids judiciously, avoiding overcrowding or overwhelming the audience with too much information.In addition to content and visual aids, engaging the audience is another vital aspect of a successful lecture. This can be achieved through various interactive techniques such as asking questions, encouraging participation, and facilitating discussions. By involving the audience actively, the lecture becomes more dynamic and memorable, leaving a lasting impression on the listeners.Moreover, rehearsal is essential to ensure a smooth delivery on the day of the lecture. Practicing the presentation multiple times helps the speaker become familiar with the material, refine their delivery style, and anticipate potential challenges or questions from the audience. Rehearsal also provides an opportunity to adjust the timing and pacing of the lecture, ensuring that it fits within the allocated time frame.On the day of the lecture, it's essential to arrive early to set up equipment, test audio-visuals, and make any last-minute adjustments. Greeting the audience warmly and establishing a rapport creates a welcoming atmosphere, setting the tone for the rest of the lecture. During the presentation, maintaining eye contact, speaking clearly and confidently, and using appropriate body language are key aspects of effective communication.Finally, after the lecture, soliciting feedback from the audience helps to evaluate its effectiveness and identify areas for improvement. Whether through verbal comments, written surveys, or online polls, feedbackprovides valuable insights that can inform future lectures and enhance the overall learning experience.In conclusion, planning a lecture involves several steps, including selecting a topic, conducting research, outlining the content, preparing visual aids, engaging the audience, rehearsing the presentation, delivering it effectively, and soliciting feedback. By following these steps diligently, a well-planned lecture can educate, inspire, and leave a lasting impact on the audience.。

Risk Premia complicates matters
9 Congress gives out tax bennies, but the market sets the price (the rate of implicit tax that is paid through lower pretax returns). The implicit tax rate is the same for everyone, regardless of their marginal explicit tax rate. Congress giveth, but they can taketh away, too…a tax disadvantaged asset is worth less (and will have to pay a higher yield = NEGATIVE implicit taxes) PPE: implicit taxes may not be observable, b/c we don’t have a BENCHMARK Implicit taxes are not paid to IRS, but to a TRANSFER AGENT Yields differ because of taxes, but also because of RISK. You can’t calculate the implicit taxes until you strip out the risk premium. High tax bracket TPs should pay implicit taxes; low bracket TPs should not. Taking implicit taxes into consideration increases PROGRESSIVITY It may be possible to exploit differential tax treatment to create a sure profit. This is what we call TAX ARBITRAGE.
Let’s have an auction. Here are the facts.
• • • • 1 year time horizon Only 2 investments exist: Bond A and Bond B Both bonds have a $1,000 face and will pay $100 in interest at the EOY Mommy always liked you better Congress likes Bond A better than Bond B, and has 5 alternative ways of conveying their feelings – Interest on A is exempt from tax, OR – ½ of interest on A is exempt from tax, OR – Purchasers of Bond A get a 10% tax credit (based on the face amount of the bond) against their income tax in the year of purchase, OR – Purchasers of Bond A get to deduct the cost of the bond against their TI in the year of purchase (but this doesn’t reduce their AB in the bond), OR – Purchasers are taxed on 1/3 of income in year of receipt (+ 1/3 in Yrs #2 + #3) Bond B sells for $1,000…what would you pay for Bond A in each alternative Oops…Teams 1-5 have a 10% tax rate, Teams 6-10 = 25%
• Already talked about double/triple tax (DRD discussion in Class 3) • Partnerships (and S Corps) are flow-through entities…no entity level tax is paid • The choice of entity depends on – Comparison of tax rates on “owners” (Tp) vs. corporations (Tc) – Duration (n) that funds will stay in the “business” (P/S or corporation) – Tax that will be paid on extraction of funds from corporation (Ts) – Non-tax factors – Note: PT ROR (R) is also a factor in the calculations, but presumably is the same for both investments
• •
Principles of Te and Ti (ignoring risk premia)
• • • For a fully taxable asset, there are no implicit taxes (Ti = 0) For a fully tax-exempt asset, there are no explicit taxes (Te = 0) Implicit taxes = extent to which the pretax return on an asset is less than the pretax return on the benchmark, i.e. a fully taxable asset (Ti = Rb – R). – Ti always has to be derived or inferred. Explicit taxes = extent to which the pretax return on an asset is greater than that on a tax-exempt asset. (Te = R – Re). – Note, this would rarely (if ever) be the same as the statutory rate. One would expect it to be < the statutory rate because the “marginal investor” is not subject to the highest tax rate. SW calculates the Ti rate with respect to Rb. This is necessary to satisfy the condition that SW has set that Ti + Te should be the same for all assets (assuming perfectly competitive markets)

SW says there are 5 flavors of tax favoritism for investment assets
• And those would be…? – Full tax exemption muni bonds – Partial tax exemption (or a lower tax rate) capital gains – Tax credit Investment tax credit, targeted jobs credit, R&E credit, low income housing credit – Tax deductions faster than rate of decline in economic value MACRS depreciation – Income taxed at a later time than when it becomes “economic income” Unrealized income
• In the real world, there are two reasons why the R ≠ r – Taxes – Risk How does risk affect the price of an asset and why?
