This program takes two complex numbers (entered by user) as input and displays the sum of them.

Example: Program to add two complex numbers entered by user

```#include <iostream>
using namespace std;
class complex_number  {
public :
int real, imag;
};
int main()  {
complex_number num1, num2, sum;
//getting the value of first complex number from user
cout << "Enter real and imaginary parts of first complex number:"<<endl;
cin >> num1.real >> num1.imag;
//getting the value of second complex number from user
cout << "Enter real and imaginary parts of second complex number:"<<endl;
cin >> num2.real >> num2.imag;
//addition of real and imaginary parts of complex numbers entered by user
sum.real = num1.real + num2.real;
sum.imag = num1.imag + num2.imag;
//displaying the sum of complex numbers
if ( sum.imag >= 0 )
cout << "Sum of two complex numbers = " << sum.real << " + " << sum.imag << "i";
else
cout << "Sum of two complex numbers = " << sum.real << " - " << sum.imag << "i";
return 0;  }```

Output

```Enter real and imaginary parts of first complex number:
4 6
Enter real and imaginary parts of second complex number:
2 3
Sum of two complex numbers = 6 + 9i```
