还有C语言支持以下赋值运算符：
| 运算符 | 描述 | 示例 |
|---|---|---|
| = | 简单的赋值操作符，分配值从右边的操作数到左侧的操作数 | C = A + B 将分配值 A + B 到 C |
| += | ADD与赋值运算符，它增加右操作数左操作数并分配结果左操作数 | C += A 相当于 C = C + A |
| -= | 减法与赋值运算符，它从左侧的操作数减去右操作数和分配结果到左操作数 | C -= A 相当于 C = C - A |
| *= | 乘法与赋值运算符，它乘以右边的操作数与左操作数和分配结果左操作数 | C *= A 相当于 C = C * A |
| /= | 除法与赋值运算符，它把左操作数与右操作数和分配结果左操作数 | C /= A 相当于 C = C / A |
| %= | 模量和赋值运算符，它需要使用两个操作数的模量和分配结果左操作数 | C %= A 相当于 C = C % A |
| <<= | 左移位并赋值运算符 | C <<= 2 和 C = C << 2 一样 |
| >>= | 向右移位并赋值运算符 | C >>= 2 和 C = C >> 2 一样 |
| &= | 按位与赋值运算符 | C &= 2 和 C = C & 2 一样 |
| ^= | 按位异或并赋值运算符 | C ^= 2 和 C = C ^ 2 一样 |
| |= | 按位或并赋值运算符 | C |= 2 和 C = C | 2 一样 |
试试下面的例子就明白了可用C语言编程的所有赋值运算符：
#include <stdio.h>
main()
{
int a = 21;
int c ;
c = a;
printf("Line 1 - = Operator Example, Value of c = %d", c );
c += a;
printf("Line 2 - += Operator Example, Value of c = %d", c );
c -= a;
printf("Line 3 - -= Operator Example, Value of c = %d", c );
c *= a;
printf("Line 4 - *= Operator Example, Value of c = %d", c );
c /= a;
printf("Line 5 - /= Operator Example, Value of c = %d", c );
c = 200;
c %= a;
printf("Line 6 - %= Operator Example, Value of c = %d", c );
c <<= 2;
printf("Line 7 - <<= Operator Example, Value of c = %d", c );
c >>= 2;
printf("Line 8 - >>= Operator Example, Value of c = %d", c );
c &= 2;
printf("Line 9 - &= Operator Example, Value of c = %d", c );
c ^= 2;
printf("Line 10 - ^= Operator Example, Value of c = %d", c );
c |= 2;
printf("Line 11 - |= Operator Example, Value of c = %d", c );
}
当编译和执行上面的程序就产生以下结果：
Line 1 - = Operator Example, Value of c = 21 Line 2 - += Operator Example, Value of c = 42 Line 3 - -= Operator Example, Value of c = 21 Line 4 - *= Operator Example, Value of c = 441 Line 5 - /= Operator Example, Value of c = 21 Line 6 - %= Operator Example, Value of c = 11 Line 7 - <<= Operator Example, Value of c = 44 Line 8 - >>= Operator Example, Value of c = 11 Line 9 - &= Operator Example, Value of c = 2 Line 10 - ^= Operator Example, Value of c = 0 Line 11 - |= Operator Example, Value of c = 2
