When parsing an expression, an operator which is listed on some row will be bound tighter (as if by parentheses) to its arguments than any operator that is listed on a row further below it. For example, the expression *p++ is parsed as *(p++), and not as (*p)++. ...

正整数:原、反、补码都相同;负整数表示方法:原码:直接将数值按照正负数的形式翻译成⼆进制得到的就是原码;反码:将原码的符号位不变,其他位依次按位取反就可以得到反码;补码:反码+1就得到补码。补码得到原码也是可以使用:符号位不变,取反,+1的操作。
operands that specifies computation of a value, or that designates an object or a function, or that generates side effects, or that performs a combination thereof. The value computations of the operands of an operator are sequenced before the value computation of the result of the operator. ...
