二级易错点
(27)调用函数时,当实参和形参都是简单变量时,它们之间数据传递的过程是()。
A)实参将其值传递给形参,调用结束时形参再将其值回传给实参B)实参将其地址传递给形参,调用结束时形参再将其地址回传给实参C)实参将其地址传递给形参,并释放原先占用的存储单元D)实参将其值传递给形参,调用结束时形参并不将其值回传给实参【解析】本题考查函数实参和形参之间是怎样传递数值的。
实参向形参传递数据的方式有两种:①如果实参传递给形参的是变量的值,就是进行的数值传递;②如果实参传递给形参的是变量的地址,就是进行地址传递。
在调用函数的时候,通过将值赋给实参,实参再将值赋给形参,从而执行函数体,但是函数体的执行并不影响实参,因而调用结束时形参并不将其值回传给实参。
(36)以下有关宏替换的叙述不正确的是()。
A)使用宏定义可以嵌套B)宏定义仅仅是符号替换C)双引号中出现的宏名不替换D)宏名必须用大写字母表示【解析】本题考查宏替换的规则。
宏替换分为简单的字符替换和带参数的宏替换两类。
使用宏时应注意以下几点:①宏定义仅仅是符号替换,不是赋值语句,因此不做语法检查;②为了区别程序中其他的标识符,宏名的定义通常用大写字母,但不是必须用大写;③双引号中出现的宏名不替换;④使用宏定义可以嵌套,即后定义的宏中可以使用先定义的宏。
(30)若有以下定义,则对a数组元素的正确引用是()。
int a[5],*p=a;A)*&a[5]B)*a+1C)*(p+5)D)*(a+2)【解析】本题考查通过指针引用数组元素。
选项A、B没有这种引用形式;选项C,*(p+5)是引用数组的第6个元素,而数组一共有5个元素,出现越界;选项D,*(a+2)引用数组的第3个元素(38)设有以下说明语句:struct stu{ int a;float b;}stutype;则以下叙述错误的是()。
A)struct是结构类型关键字B)struct stu是用户定义的结构类型C)stutype是用户定义的结构类型D)a、b都是结构成员名【解析】本题主要考查结构类型的定义:struct是结构体类型的关键字;struct stu是结构体类型名;a、b都是结构体成员名;stutype是结构变量名。

国二易错点
1.树是简单的非线性结构,所以二叉树作为树的一种也是一种非线性结构。
2.栈是按先进后出的原则组织数据的。
队列是先进先出的原则组织数据。
3.循环队列的队头指针与队尾指针都不是固定的,随着入队与出队操作要进行变化。
因为是循环利用的队列结构所以对头指针有时可能大于队尾指针有时也可能小于队尾指针。
4.一般较优秀的软件设计,应尽量做到高内聚,低耦合,即减弱模块之间的耦合性和提高模块内的内聚性,有利于提高模块的独立性。

专升本计算机试题常见易错点剖析与解答心得交流
专升本计算机试题常见易错点剖析与解答心得交流计算机专升本考试对于考生来说是一个重要的里程碑。
在备考过程中,我们常常会遇到一些常见的易错点,这些错误可能会影响我们的成绩。
因此,本文将剖析常见的易错点,并提供解答和心得交流,帮助大家更好地备考专升本计算机考试。
1. 数据类型转换问题在计算机科目中,经常会遇到数据类型转换的问题。
这是一个易错点,因为不同数据类型之间的转换规则不同。
比如,在C语言中,整型数据与浮点型数据的运算结果会按照一定的规则进行转换。
解答:要正确处理数据类型转换问题,我们需要掌握各种数据类型之间的转换规则。
可以通过查阅相关资料或者通过编程练习来加深理解。
同时,在解答试题时,要仔细阅读题目,判断所给数据类型并正确进行转换,避免因类型不匹配而出错。
心得交流:在备考过程中,我发现通过编程实践可以更好地加深对数据类型转换的理解。
因此,我编写了一些相关的小程序,通过手动进行数据类型转换来加强记忆和掌握规则。
这种实践结合理论学习的方式对我很有效,希望对大家也有所帮助。
2. 数组越界问题在计算机编程中,数组是一种常见的数据结构。
在编写程序时,经常会遇到数组访问越界的问题,这是一个容易犯的错误。
解答:要避免数组越界问题,我们需要了解数组的下标范围以及访问数组元素的正确方式。
在写程序时,要注意数组下标是否超出规定范围,并且要考虑边界情况。
可以通过在程序中添加边界检查来避免数组越界错误的发生。
心得交流:我在备考过程中,通过编写一些涉及数组操作的程序,加深了对数组访问的理解。
我发现在编程时多添加一些边界检查的代码可以有效地避免数组越界问题。
此外,阅读相关的代码示例和经典案例也有助于提高对数组操作的正确性把握。
3. 逻辑错误逻辑错误是编程过程中容易出现的一种错误。
它常常是由于程序员对问题的分析不准确或者对逻辑关系理解不深造成的。
解答:要避免逻辑错误,我们需要对程序要求进行准确的分析,理清逻辑关系。
在思考和编写代码时,可以通过流程图、伪代码等方式进行抽象和逻辑分析,提高代码的准确性。
