Insertion Overload Example in C++


C++ is able to input and output the built-in data types using the stream extraction operator >> and the stream insertion operator <<. The stream insertion and stream extraction operators also can be overloaded to perform input and output for user-defined types like an object.

Example Program:

Here is the simple program using insertion overloading in C++.

Source Code

using namespace std;
class Complex
public :
    int real;
    int img;
    friend ostream & operator << (ostream &o,Complex &c1);
ostream & operator << (ostream &o,Complex &c1)
    return o;
int main()
    Complex c1;
    return 0;
