上面左边是c++,右边是c语言,右边编译没问题,是因为在c中那三个变量a,有一个是定义变量,另外两个是声明,c会自动给它加上extern,所以可以编通过,而在c++中,必须自己加上另外两个extern,不然编译不通过 using namespace std相当于JAVA中的import某个类,叫做声明命令空间,之后才能用cout cout <<“hello world” <...

using bitwise operator XOR is a programming trick that is usually asked in technical interviews. It does not use a third temp variable for swapping values between two variables. This solution only works for unsigned integer types. It won't work for floating point, pointers, and struct/union ...

联合(union)是一种节省空间的特殊的类,一个 union 可以有多个数据成员,但是在任意时刻只有一个数据成员可以有值。当某个成员被赋值后其他成员变为未定义状态。联合有如下特点:默认访问控制符为 public 可以含有构造函数、析构函数 不能含有引用类型的成员 不能继承自其他类,不能作为基类 不能含有虚函数 匿名union...
