c语言算术运算符和赋值运算符（C语言运算符之算术运算符）

算术运算符：

下表是显示了C语言支持的所有算术运算符。假设变量A的值是10，变量B的值是20。

创建源代码文件：marithmetic_operators.c，代码如下：

#include <stdio.h>

void main() {

int a = 21;

int b = 10;

int c ;

c = a b;

printf("Line 1 - Value of c is %d\n", c );

c = a - b;

printf("Line 2 - Value of c is %d\n", c );

c = a * b;

printf("Line 3 - Value of c is %d\n", c );

c = a / b;

printf("Line 4 - Value of c is %d\n", c );

c = a % b;

printf("Line 5 - Value of c is %d\n", c );

c = a ;

printf("Line 6 - Value of c is %d\n", c );

c = a--;

printf("Line 7 - Value of c is %d\n", c );

}

执行上面的代码，得到如下结果:

Line 1 - Value of c is 31

Line 2 - Value of c is 11

Line 3 - Value of c is 210

Line 4 - Value of c is 2

Line 5 - Value of c is 1

Line 6 - Value of c is 21

Line 7 - Value of c is 22
