算術(shù)運算符：

下表是顯示了C語言支持的所有算術(shù)運算符。假設(shè)變量A的值是10，變量B的值是20。

創(chuàng)建源代碼文件：marithmetic_operators.c，代碼如下：

#include <stdio.h>

void main() {

int a = 21;

int b = 10;

int c ;

c = a + b;

printf("Line 1 - Value of c is %dn", c );

c = a - b;

printf("Line 2 - Value of c is %dn", c );

c = a * b;

printf("Line 3 - Value of c is %dn", c );

c = a / b;

printf("Line 4 - Value of c is %dn", c );

c = a % b;

printf("Line 5 - Value of c is %dn", c );

c = a++;

printf("Line 6 - Value of c is %dn", c );

c = a--;

printf("Line 7 - Value of c is %dn", c );

}

執(zhí)行上面的代碼，得到如下結(jié)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
