Answer to Question #180760 in C++ for RAMAKRISHNA

Question

Write a program to perform binary operator overloading for a class named "data". The details of operators to be overloaded are:

+ will subtract the numbers

- will divide the numbers

*will add the numbers

/ will multiply the numbers.

Answer 1

#include<iostream>
using namespace std;

class ComplexNumber {
   private:
    float real;
    float imag;

   public:
    // Constructor to initialize real and imag to 0
    ComplexNumber() : real(0), imag(0) {

    }

    void input() {
        cout << "Enter real and imaginary parts respectively: ";
        cin >> real;
        cin >> imag;
    }

    // Overload the + operator
    ComplexNumber operator + (const ComplexNumber& obj) {
        ComplexNumber temp;
        temp.real = real + obj.real;
        temp.imag = imag + obj.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() {
    ComplexNumber complex1, complex2, result;

    cout << "Enter first complex number:\n";
    complex1.input();

    cout << "Enter second complex number:\n";
    complex2.input();

   // complex1 calls the operator function
   // complex2 is passed as an argument to the function
    result = complex1 + complex2;
    result.output();

    return 0;
}
