所有赋值运算符的列表:
<ul>=:分配,如 x = 5
+=:加法赋值,如 x += 3(等同于 x = x + 3)
-=:减法赋值,如 x -= 3(等同于 x = x - 3)
*=:乘法赋值,如 x *= 3(等同于 x = x * 3)
/=:除法赋值,如 x /= 3(等同于 x = x / 3)
%=:模赋值,如 x %= 3(等同于 x = x % 3)
&=:按位与赋值,如 x &= 3(等同于 x = x & 3)
|=:按位或赋值,如 x |= 3(等同于 x = x | 3)
^=:按位异或赋值,如 x ^= 3(等同于 x = x ^ 3)
>>=:有符号右移赋值,如 x >>= 3(等同于 x = x >> 3)
= y
