Answer to Question #189103 in C++ for Waleed Abid

Question

C++ Program to Add Complex Numbers by Passing Structure to a Function

Answer 1

#include <iostream>
using namespace std;

typedef struct {
    double real;
    double imaginary;
} Complex;

Complex complexSum(Complex a, Complex b) {
    Complex sum;
    
    sum.real = a.real + b.real;
    sum.imaginary = a.imaginary + b.imaginary;
    
    return sum;
}

void complexPrint(Complex a) {
    if ( a.imaginary > 0 ) {
        cout << a.real << "+" << a.imaginary << "i";
    }
    if ( a.imaginary < 0 ) {
        cout << a.real << a.imaginary << "i";
    }
    if ( a.imaginary == 0 ) {
        cout << a.real;
    }
}

int main() {
    Complex z1, z2, sum;

    cout << "Please enter real and imaginary parts for the first complex number:" << "\n";
    cin >> z1.real >> z1.imaginary;

    cout << "\nPlease enter real and imaginary parts for the second complex number:" << "\n";
    cin >> z2.real >> z2.imaginary;

    sum = complexSum(z1, z2);

    cout << "\nThe sum of your complex numbers is: ";

    complexPrint(sum);

    return 0;
}
