Create a class which store the real and imaginary part of a complex number . Add two complex number and display the result . To add 2 complex number, function having two object argument and and no return values

Objective

Write a C++ program to add two Complex Numbers by passing Objects as function arguments.

Algorithm / Approach

  1. Define a class Complex with public integers r (real) and i (imaginary).
  2. Create a member function add(Complex c1, Complex c2).
  3. Inside main(), create two Complex objects c1 and c2 and read their values.
  4. Call c1.add(c1, c2) to add the real parts together, add the imaginary parts together, and print the formatted result.
main.cpp 
#include<iostream>
using namespace std;
class Complex {
 public :
 int r,i;
 void add(Complex c1, Complex c2 ) {
  int x = c1.r+c2.r;
  int y = c1.i+c2.i;
  cout<<"Sum = "<< x<<" +i"<< y;
  }
};
int main() {
 Complex c1,c2;
 cout<<"Enter Real & Imag. of Num1 :";
 cin>>c1.r>>c1.i;
 cout<<"Enter Real & Imag. of Num2 :";
 cin>>c2.r>>c2.i;
 c1.add(c1,c2);
 return 0;
}

Expected Output

Enter the Real and Imag. of Num1 :5 10
Enter the Real and Imag. of Num2 :6 20
Sum = 11 +i30

Explanation of the Program

  • Just like integers and strings, whole Objects can be passed into functions as arguments!
  • A Complex Number has a Real part and an Imaginary part (e.g., 5 + 10i). To add two complex numbers mathematically, you add the real parts together, and the imaginary parts together independently.
