在以下示例中,将名为complx的类定义为对复数进行建模,并在此类中重新定义+(加号) 运算符以添加两个复数。 // This example illustrates overloading the plus (+) operator. #include <iostream> using namespace std; class complx { double real, imag; public: complx( double real = 0., double imag ...
The comparison and copying are bitwise (similar tostd::memcmpandstd::memcpy); no constructor, assignment operator, or comparison operator are used. The weak forms(1,2)of the functions are allowed to fail spuriously, that is, act as if*this!=expectedeven if they are equal. When a compare...

We can overload constructor, it means we can create more than one constructor of class. We can use default argument in constructor. It must be public type. Example of C++ Constructor #include <iostream>usingnamespacestd;classSample{private:intX;public:// default constructorSample() {// data...
