C++ 赋值运算符
赋值运算符
赋值运算符用于给变量赋值。
在下面的例子中,我们使用赋值运算符 (=) 将值 10 赋给名为 x 的变量:
实例
int x = 10;
加法赋值运算符(+=)将值加到变量上:
实例
int x = 10; x += 5;
所有赋值运算符的列表:
| 运算符 | 例子 | 等同于 | 试一试 |
|---|---|---|---|
| = | x = 5 | x = 5 | 试一试 |
| += | x += 3 | x = x + 3 | 试一试 |
| -= | x -= 3 | x = x - 3 | 试一试 |
| *= | x *= 3 | x = x * 3 | 试一试 |
| /= | x /= 3 | x = x / 3 | 试一试 |
| %= | x %= 3 | x = x % 3 | 试一试 |
| &= | x &= 3 | x = x & 3 | 试一试 |
| |= | x |= 3 | x = x | 3 | 试一试 |
| ^= | x ^= 3 | x = x ^ 3 | 试一试 |
| >>= | x >>= 3 | x = x >> 3 | 试一试 |
| <<= | x <<= 3 | x = x << 3 | 试一试 |
