#include <iostream>

using namespace std;

typedef struct complex{
    float real;
    float imag;
}complex;

complex add(complex n1,complex n2);

int main(){
    complex n1,n2,temp;
    cout << "For 1st complex number " << endl;
    cout << "Enter real and imaginary respectively:" << endl;
    cin >> n1.real >> n1.imag;
    cout << endl << "For 2nd complex number " << endl;
    cout << "Enter real and imaginary respectively:" << endl;
    cin >> n2.real >> n2.imag;
    temp=add(n1,n2);    
    cout << "Sum: " << "(" << temp.real << ")" << "+" << "(" << temp.imag << ")" << "i";
    return 0;
}

complex add(complex n1,complex n2){
      complex temp;
      temp.real=n1.real+n2.real;
      temp.imag=n1.imag+n2.imag;
      return(temp);
}

Output

For 1st complex number
Enter real and imaginary respectively: 2.3
4.5

For 2nd complex number
Enter real and imaginary respectively: 3.4
5
Sum=(5.7) + (9.5)i
