Question

Write a program in C++ to overload ‘*’ operator?​

Answer 1

Answer:

#include <iostream>

using namespace std;

class Complex

{

  private:

    float real;

    float imag;

  public:

     Complex(): real(0), imag(0){ }

     void input()

     {

         cout << "Enter real and imaginary parts respectively: ";

         cin >> real;

         cin >> imag;

     }

     // Operator overloading

     Complex operator - (Complex c2)

     {

         Complex temp;

         temp.real = real - c2.real;

         temp.imag = imag - c2.imag;

         return temp;

     }

     void output()

     {

         if(imag < 0)

             cout << "Output Complex number: "<< real << imag << "i";

         else

             cout << "Output Complex number: " << real << "+" << imag << "i";

     }

};

int main()

{

  Complex c1, c2, result;

  cout<<"Enter first complex number:\n";

  c1.input();

  cout<<"Enter second complex number:\n";

  c2.input();

  // In case of operator overloading of binary operators in C++ programming,  

  // the object on right hand side of operator is always assumed as argument by compiler.

  result = c1 - c2;

  result.output();

  return 0;

}
