If a class contains a member that is a pointer, one should implement copy constructor. Should one implement copy constructor if a class contains a member that is a reference? -- Alex... C / C++ 7 Why operator<< should be friend or global, non-member function. by: Eric Lilja | ...
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。
