本次推文通过对C语言易错点和列举一些经典程序的复习,以此来帮助大家复习C语言。

This tweet aims to help everyone review C language by reviewing its common mistakes and listing some classic programs.

二、易错点

(一)自加表达式

a++与++a的区别

++a是先把变量的数值加上1,然后把得到的数值放到变量a中,然后再用这个++a表达式的数值。而a++是先用该表达式的数值,然后再把a的数值加上1,再放到变量a中。

(1) Self additive expression

The difference between a++and++a

++A is to first add 1 to the value of the variable, then place the resulting value in variable a, and then use the value of this++a expression. And a++first uses the value of the expression, then adds 1 to the value of a, and then places it in the variable a.

(二)逗号表达式

表达式的数值等于逗号最右边表达式的数值。

例如:

z=(2,3,4)的表达式的数值就是4;

z=2,3,4的表达式的数值就是2

(2) Comma expression

The value of an expression is equal to the value of the expression to the far right of the comma.

For example,

the value of an expression with z=(2, 3, 4) is 4;

The value of the expression z=2, 3, and 4 is 2

(三)数据输入

scanf第二部分必须是一个地址,所以需要在标识符前加上&。

(3) Data input

The second part of scanf must be an address, so you need to add&before the identifier.

三、经典程序

(一)素数的判断

下面定义一个函数来判断数据是否为素数。

(1) Judgment of Prime Numbers

Define a function below to determine whether the data is a prime number.
