蓝桥杯c 试题及答案

蓝桥杯c 试题及答案

蓝桥杯c 试题及答案蓝桥杯是中国著名的计算机竞赛,由中国计算机学会主办,每年举办一次。

其中,C语言组是比赛的一个重要环节,考察选手对于C语言程序设计的理解和应用能力。

以下是蓝桥杯C语言组试题及答案的整理,供参赛选手参考和学习。

第一题:找素数题目描述:请编写一个程序,计算给定范围内的素数个数,并输出结果。

输入:输入两个正整数n和m(1 <= n, m <= 1000,n <= m),表示要计算的范围。

输出:输出一个整数,表示该范围内的素数个数。

样例输入:2 10样例输出:4解题思路:素数是指只能被1和自身整除的整数,根据这个定义,我们可以使用一个循环来判断每个数是否为素数。

具体实现时,首先需要判断一个数n是否为素数,可以从2开始将n除以每个数,若能整除则说明n 不是素数;反之,则n是素数。

将这个判断的逻辑封装成一个函数,然后在给定的范围内遍历每个数,统计出素数的个数即可。

代码实现:```c#include <stdio.h>int isPrime(int n) {if (n <= 1) {return 0;}for (int i = 2; i * i <= n; i++) {if (n % i == 0) {return 0;}}return 1;}int countPrimes(int n, int m) {int count = 0;for (int i = n; i <= m; i++) {if (isPrime(i)) {count++;}}return count;}int main() {int n, m;scanf("%d %d", &n, &m);int result = countPrimes(n, m);printf("%d\n", result);return 0;}```参考答案如上所示,该程序通过调用判断素数的函数,并在给定范围内进行循环判断,最终输出结果。

Almost 68% of people think that the government has secret knowledge of extraterrestrial life. It is not (47) _surprising__ (surprise) that the government has come under more and more (48) pressure____ to declassify its UFO records and make them public. A variety of different groups have been involved in these efforts.One group to become involved is called CFI, the Coalition for Freedom of Information, John Podesta, who was White House Chief of Staff duri ng Bill Clinton’s (49)presidency____(president), is one of the many high-powered people active in this group. CFI’s aim is not to prove the (50) _existence___(exist) of extraterrestrial life, but to make it easier for scientists in general to study unexplained aerial phenomena. Podesta and his group has asked the Pentagon to declassify its UFO records and therefore provide scientists (51) with____ data that will help in the study of UFOs.CFI has requested the release of information on several UFO cases, starting with the Kecksburg, Pennsylvania, incident. This incident took (52) __place__ in 1965 when a large acorn-shaped object, the size of a small car, crashed in Pennsylvania. Some analysts say it could have been the spacecraft Kosmos 96 that had been launched towards Venus by the Soviet Union, but failed to escape Earth’s (53) g ravity____. Others say the object did not look anything like spacecraft built on Earth in 1965.(54) Additionally___, the people of Kecksburg want to know what happened. On that (55) afternoon____, hundreds of eyewitnesses watched a fiery streak of light descend from the sky towards Earth. Officials explained that nothing was found or recovered and that maybe the fireball in the sky was a meteor. But many witnesses say they saw a number of military personnel from the Army and the Air Force search the woods, and later that evening, saw a large militarytractor-trailer coming from the area carrying a large object under a tarp.Part IV Reading Comprehension (40 marks)Read the following passage. Each passage is followed by several questions. Respond to the questions using information from the passage. Remember to write the answers on the answer sheet.Section A (10 marks)Questions 56-60 are based on the following passage.The average automatic teller machine (ATM) is not very smart. It will give money to anyone who has the right card and punches four or five keys in the right order. Some analysts estimate that as many as 30% of ATM transaction worldwide are cases of theft. To increase security at cash machines, some banks have tried to make their ATMs a little smarter. A small camera on the machine looks directly into the eye of every customer. It scans one iris and compares the tiny patterns of ridges, dots, and other features to a code in its computer. If there is a match, the ATM will start counting out cash. If not, a message is automatically sent to the nearest police station.Iris-scanning is one fast-growing form of biometric identification --- determining who someone is by examining features the body. One of the earliest biometric techniques was fingerprinting. The line on fingerprints are unique to each person, so not even identical twins have the same fingerprints. Fingerprinting has become famous as a way of finding out who committed a crime, but it very often fails. A careful criminal can swear gloves, avoid touching thing, or even alter his fingerprints by burning, cutting, or scraping them. In the search for a more reliable system, security experts have focused on the eye.Like a fingerprint, every iris is, for all practical purposes, unique. Each person’s right iris is even different from his or her left one. A low-cost digital camera, like the kind installed at ATM machines, can easily detect hundreds of different features in the iris. The chance of two irises having the same features is close to zero. Tests have shown that iris-scanners are very hard to fool. They can tell the difference between a real iris and a false one. They can see right through colored contact lenses, eyeglasses, and even mirrored sunglasses. Although many criminal are willing to burn or cut their fingers in pursuit of the perfect crime, few would be willing or able to alter their irises.T o make iris-scanning work, a computerized database has to match certain iris features with certain people. This means that each A TM customer has to allow a bank to photograph his or her iris and keep that highly personal information in a computer. Some people have worried, however, that an increased use of iris-scanning will lead to a dangerous loss of privacy. By mountingiris-scan cameras in public places, governments could track a private citizen all day long without the person’s knowledge. This would be a great advantage to the police, but it could also giv e corrupt officials a new way to control their opponents. The military’s development of tiny robots suggests that government iris-scanners could even invade private homes!Questions 56-60Complete the summary with words from the passage, changing the form where necessary, with only one word for each blank.Section B (10 marks)Questions 61-65 are based on the following passage.Seed catalogues feature hundreds of flowering species. For the persons just beginning garden this can be bewildering, and below are the details of some popular choices, nearly all of which should be sown in the spring. With the exception of busy lizzies, which need a little care, they are all very easy to grow from seed.DahliasThese are sturdy plants bearing showy flowers in a wide range of rather gaudy colors. Sow in a frame in April and plant the seedlings out when frosts are over. Dahlias flower throughout the summer and into the autumn. When autumn frosts begin to make them look unhappy, you should dig up the tuberous roots and save them. A frost-free loft, shed or garage is the ideal place. The following spring you plant the tubers instead of sowing seed again.LupinsLupins are hardy perennials. This means that the plants will stay in your garden and carry on flowering year after year. Seed sown in April will usually give you some spikes of colors in the first summer, and year by year the plants get bigger and the flowering stems get taller and grander. Selective breeding has led to the introduction of some fine, bicolored varieties in some dazzling shades. The short-lived flowers make a real misunderstanding spectacle.Busy lizziesLike dahlias, busy lizzies need to be started offunder glass, as they cannot stand frost, and pantingout is best done in May. Outdoor flowering ends inSeptember, so beat the frosts and bring your favoritespecimens indoors to give your home some sintercolor! Indoors they will carry on floweringindefinitely, though you may like to plant them outagain when spring returns. Like pansies (below) they do very well in sun or shade, but the soil must be moist. Most varieties grow to be a height of only 20 cm or so.PotentillasPotentillas are hardy shrubs. In other words, the woody branches spring from groundlevel —there is no central trunk. Seed is probably best sown in autumn, in which case you should keep the plants in a sheltered spot until April offers favorable conditions for planting out. Once flowering begins in early summer the best varieties (such as Melton Fire) will stay in bloomATM transactions are often cases of theft, where an unauthorized user takes (56) __money_. To decrease insecurity, some banks have installed iris-scanning machines at ATMs. These small cameras scan t he user’s iris, recording its features and (57) _comping___ them to a digital file. Every person has a (58) _ unique ___ iris, making iris identification highly reliable. Earlier efforts at biometric identification often relied on fingerprints. However, fingerprints can easily be (59) altered____ through cutting, burning or scrapping. Iris scanners are so effective that they can even see through contact lenses and mirrored sunglasses. Use of iris scanners would provide great advantages to the police. However,others worry about a loss of (60) ____.almost ceaselessly for years on end while at the same time spreading out to provide ground cover or a low hedge.PansiesPansies have a good long flowering season year after year, and some varieties can be sown in spring to give truly splendid results the first autumn. Unlike dahlias and lupins, which can easily grow a meter tall, pansies grow no higher than 10 or 20 cm. Their soil, position and moisture requirements are just like those of busy lizzies but pansies differ in being hardy. Give them a try!Questions 61-63Decide whether the following statements are true (T) or false (F) according to the passage.61. Both dahlias and lupins, which are sown in April, need protecting from frost.62. Brought indoors in autumn, dahlias, busy lizzies and potentillas will carry on flowering almost non-stop.63. Among all the flowers busy lizzies are not very easy to grow from seed.Section C (10 marks)Questions 66-70 are based on the following passage.When looking for love, people may go to some extreme lengths. They might go on blind dates set up by family and friends. They might write personal ads to place in newspapers. Or they might use a computer to help them in their search for a soul mate by joining an online dating services. Some people have even tried to find their perfect match through game shows on television. Many of these TV dating shows, including The Bachelor and Who Wants to Marry a Millionaire? have proved to be ratings blockbusters, with millions of viewers watching each week to find out which of the contestants will find true love.Of all these game shows, perhaps the one with the most unexpected ending was Mr. Right, which was shown in England in 2002. On the show, a bachelor, thirty-five-year-old Lance Gerrard-Wright, dated fifteen women to find the one who was his ideal partner. The host of the show was Ulrika Johnson, an English celerity originally from Sweden. For seven weeks on the show, Gerrard-Wright took turns going on dates with each of the women, taking them to expensive restaurants and exotic locations. He even met the women’s families and introduced them to his own. Then at the end of each episode, he would choose between one and three of the contestants with whom he had felt the least compatible, and say goodbye to them.At one point during the series, one contestant volunteered to leave because she said she didn’t find him attractive. After two dates she said she had had enough, and she couldn’t see it working. ―He wasn’t my cup of tea.‖ In another episode the woman he was on a date with burst into tears when he called her by another contestant’s name. ―You called me by another girl’s name. I can’t bel ieve you did that. I really liked you,‖ she sobbed.But in the final episode, the woman he eventually chose decided she didn’t want to marry him after all. ―I think you’ve chosen me because you have to choose someone,‖ she said. Maybe this was because she already knew he had fallen in love---with the show’s host!After leaving the show, Gerrard-Wright and Johnson were seen dining together and attending parties around London more and more often. Finally, on May 1, 2003, Gerrard-Wright proposed to Johnson o n the steps of St. Paul’s Cathedral. And she accepted his proposal right away, although it was a conditional acceptance. Johnson has two children from previous relationships—aneight-year-old son, Cameron, and a two-year-old daughter, Bo. She had to make sure that they agreed to the marriage. Luckily, they did. Gerrard-Wright said, ―In the end the show did work for me. I grabbed an opportunity to get a girlfriend and I did. Ulrika’s gorgeous.‖Questions 66-68Complete the following sentences with information given in the passage in a maximum of 2 words for each blank.66. Lance Gerrard-Wright went to ____ to go on the show Mr. Right in order to find his perfect match.67. On the show, Lance had the opportunity to date many gorgeous women among whom there might be one that he was almost ____.68.

Ulrika consulted her parents before she made her decision.D. The women met Lance’s family.70. What happened after seven weeks of doing the show?A. All of the women found their beloved.B. Lance started to date with the show’s host.C. One of the women on the show couldn’t help crying.D. Ulrika asked Lance to marry her.Section D (10 marks)Questions 71-75 are based on the following passage.Alaska is disappearing slowly but surely. Since the 1950s, it is estimated that as much as 15 percent of Alaska’s area has disappeared. But how can a whole state be disappearing?One reason for Alaska’s gradual disappearance is the melting its glaciers. According t o one geologist at the US Geological Survey, about 98 percent of Alaska’s glaciers are either unmoving or diminishing. This diminishing seems mainly due to the increase in global temperatures. Since the 1960s, the average year-round temperature has increased by 5℉. Furthermore, the average winter temperature has increased by 8℉. Presently, an estimated 24 cubic miles of ice is disappearing from Alaskan glaciers every year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 2.5 to 10℉by the year 2010.Another problem contributing to Alaska’s gradual disappearance is its permafrost. (74) Much of the land in Alaska was permanently frozen, or frozen for most of the year, thus maintaining its integrity. Now, the thawing permafrost is causing a number of problems on land. Roads and utility poles are collapsing. Also, the hard permafrost which originally prevented beaches from eroding during violent storms is now melting. Affected villages are forced to relocate. For villages on small low islands, one terrible storm could wipe out the entire community.The melting permafrost and increasing temperature are also having a negative impact on the forests of Alaska. As the permafrost under the forests melts, in sects that normally don’t turn upuntil the warmer seasons are appearing sooner. The spruce-bark beetle, for example, is increasing in numbers as a result of global warming. It usually takes about two years for these beetles to grow and reproduce in a very cold weather. However, due to the increase in temperatures, spruce-bark beetles are damaging as many trees in one year as they previously damaged in two. At this rate, Alaska’s forest won’t survive the turn of the century.Some scientists believe that human activity is linked to a global increase in weather temperature. Whether the rising temperature are caused by human activity or natural changes, the fact remains that Alaska is warming. Some others argue that global warming may be a normal trend on the Earth’s temperature chart. (75) One theory argues that we are near the end of aso-called ―Little Ice Age‖, and the return of the glaciers is natural result of this cycle. Whether natural or produced by humans, there is little hope for the immediate future of glaciers as we know them. Horribly, this could be a preview of what will happen to the rest of the world in the next century.Questions 71-73Answer the following questions briefly according to the passage.71. What are disappearing in Alaska actually?72. How much ice is melting each year according to the survey?73. Why do insects damage more trees than before?Questions 74-75Translate the underlined sentences in the passage into Chinese.74. Much of the land in Alaska was permanently frozen, or frozen for most of the year, thus maintaining its integrity75. One theory argues that we are near the end of a so-called ―Little Ice Age‖, and the return of the glaciers is natural result of this cycle. Whether natural or produced by humans, there is little hope for the immediate future of glaciers as we know them.Part V Translation (10 marks)Translate the following sentences into English, using the hints given in brackets.

题目标题:猜年龄
美国数学家维纳(N.Wiener)智力早熟,11岁就上了大学。他曾在1935~1936年应邀来中国清华大学讲学。
一次,他参加某个重要会议,年轻的脸孔引人注目。于是有人询问他的年龄,他回答说:
“我年龄的立方是个4位数。我年龄的4次方是个6位数。这10个数字正好包含了从0到9这10个数字,每个都恰好出现1次。”
仔细阅读程序的输入、输出要求,千万不要输出没有要求的、多余的内容,例如:“请您输入xx数据:”。
建议仔细阅读示例,不要想当然!
程序处理完一个用例的数据后,立即退出(return 0),千万不要循环等待下一个用例的输入。
程序必须使用标准输入、标准输出,以便于机器评卷时重定向。

标题:三部排序
一般的排序有许多经典算法,如快速排序、希尔排序等。
但实际应用时,经常会或多或少有一些特殊的要求。我们没必要套用那些经典算法,可以根据实际情况建立更好的解法。
比如,对一个整型数组中的数字进行分类排序:
提交时,注意选择所期望的编译器类型。
标题:核桃的数量
小张是软件项目经理,他带领3个开发组。工期紧,今天都在加班呢。为鼓舞士气,小张打算给每个组发一袋核桃(据传言能补脑)。他的要求是:
1.各组的核桃数量必须相同
2.各组内必须能平分核桃(当然是不能打碎的)
3.尽量提供满足1,2条件的最小数量(节约闹革命嘛)
注意:所有依赖的函数必须明确地在源文件中#include <xxx>,不能通过工程设置而省略常用头文件。
所有源码必须在同一文件中。调试通过后,拷贝提交。

选手必须通过浏览器方式提交自己的答案。选手在其它位置的作答或其它方式提交的答案无效。
试题包含三种类型:“结果填空”、“代码填空”与“程序设计”。
他把1,2,3,...16这16个数字填写在4 x 4的方格中。
如图p1.jpg所示,即:
16 ? ? 1316 3 213
? ? 11 ?5811 10
9 ? ? *96 712
? 15 ? 1 415 14 1
表中有些数字已经显露出来,还有些用?和*代替。
请你计算出?和*所代表的数字。并把*所代表的数字作为本题答案提交。

从我做起振
我做起振兴
做起振兴中
起振兴中华
比赛时,先站在左上角的写着“从”字的格子里,可以横向或纵向跳到相邻的格子里,但不能跳到对角的格子或其它位置。一直要跳到“华”字结束。
要求跳过的路线刚好构成“从我做起振兴中华”这句话。
请你帮助小明算一算他一共有多少种可能的跳跃路线呢?
答案是一个整数,请通过浏览器直接提交该数字。

题目标题:打印十字图
小明为某机构设计了一个十字型的徽标(并非红十字会啊),如下所示(可参见p1.jpg)
{
int temp;
temp=*a;
*a=*b;
*b=temp;
}
void myfunc(int a, int b)
{
int m,n,r;
if(a<b) swap(&a,&b);
m=a;n=b;r=a%b;
while(r!=0)
{
a=b;b=r;
r=a%b;
}
printf("%d\n",b); //最大公约数
使得负数都靠左端,正数都靠右端,0在中部。注意问题的特点是:负数区域和正数区域内并不要求有序。可以利用这个特点通过1次线性扫描就结束战斗!!
以下的程序实现了该目标。
其中x指向待排序的整型数组,len是数组的长度。
void sort3p(int* x, int len)
{
int p = 0;
int left = 0;
结果填空题:要求选手根据题目描述直接填写结果。求解方式不限。不要求源代码。
把结果填空的答案直接通过网页提交即可,不要书写多余的内容。
代码填空题:要求选手在弄清给定代码工作原理的基础上填写缺失的部分,使得程序逻辑正确、完整。所填写的代码不超过一条语句(即中间不能出现分号)。
把代码填空的答案(仅填空处的答案,不包括题面已存在的代码或符号)直接通过网页提交即可,不要书写多余的内容。
程序从标准输入读入:
a b c
a,b,c都是正整数,表示每个组正在加班的人数,用空格分开(a,b,c<30)
程序输出:
一个正整数,表示每袋核桃的数量。
例如:
用户输入:
2 4 5
程序输出:
20
再例如:
用户输入:
3 1 1
程序输出:
3

标题:振兴中华
小明参加了学校的趣味运动会,其中的一个项目是:跳格子。
地上画着一些格子,每个格子里写一个字来自如下所示:(也可参见p1.jpg)
注意选择自己使用的编译环境。
题目标题:公约数公倍数
我们经常会用到求两个整数的最大公约数和最小公倍数的功能。
下面的程序给出了一种算法。
函数myfunc接受两个正整数a,b
经过运算后打印出它们的最大公约数和最小公倍数。
此时,调用myfunc(15,20)
将会输出:
3
60
//交换数值
void swap(int *a,int *b)
注意选择自己使用的编译环境。
使用ANSI C/ANSI C++标准,不要依赖操作系统或编译器提供的特殊函数。
程序设计题目:要求选手设计的程序对于给定的输入能给出正确的输出结果。考生的程序只有能运行出正确结果才有机会得分。
注意:在评卷时使用的输入数据与试卷中给出的示例数据可能是不同的。选手的程序必须是通用的,不能只对试卷中给定的数据有效。
