Question

Given two complex numbers, find the sum of the complex numbers using operator overloading.

Write an operator overloading function

    ProblemSolution operator + (ProblemSolution const &P)

which adds two ProblemSolution objects and returns a new ProblemSolution object.

Input

    12 -10
     -34 38

    where,

• Each row is a complex number.
• First element is real part and the second element is imaginary part of a complex number.

Output

    -22 28

Two complex numbers are 12-10i and -34+38i.

Sum of complex numbers are = -22+28i.

Assume that,

• Real and imaginary numbers are integers within the range [-2,000,000,000 to 2,000,000,000]

#include<iostream>
using namespace std;

class ProblemSolution {
private:
int real, imag;
public:

ProblemSolution(int r = 0, int i =0) {
real = r; imag = i;
}

void displayResult(){
cout<<real<<" "<<imag;
}

   //write your code here

};

int main()
{   
int real,imag;
cin>>real>>imag;
ProblemSolution problemSolution1(real, imag);
cin>>real>>imag;
ProblemSolution problemSolution2(real,imag);
ProblemSolution problemSolution3 = problemSolution1 + problemSolution2;
problemSolution3.displayResult();
}

//ProblemSolution.cpp

#include<iostream>
using namespace std;

class ProblemSolution
{
   private:
       int real, imag;
   public:

   ProblemSolution(int r = 0, int i =0)
   {
       real = r; imag = i;
   }
   void displayResult()
   {
      
       cout<<real;
       //if imaginary part is positive
       //display + symbol then imaginary part.
       if(imag >= 0)
       {
           cout<<"+";
           cout<<imag<<"i";
       }
       //if negative display negative
       //and convert the imag part to positive using - operator
       else
       {
           cout<<"-";
           cout<<-imag<<"i";
       }
      
   }
   //overloaded operator +
   ProblemSolution operator + (ProblemSolution const &P)
   {
       //create new object of ProblemSolution with
       //addition real part of calling object and passed real value as new real part of the result.
       //same occurs for imaginary part.
      
       ProblemSolution res(real + P.real, imag+ P.imag);
       //return the result
       return res;
   }
};

int main()
{   
   int real,imag;
   cin>>real>>imag;
   ProblemSolution problemSolution1(real, imag);
   cin>>real>>imag;
   ProblemSolution problemSolution2(real,imag);
   ProblemSolution problemSolution3 = problemSolution1 + problemSolution2;
   cout<<"Two Complex Numbers are ";
   problemSolution1.displayResult();
   cout<<" and ";
   problemSolution2.displayResult();
   cout<<endl;
   cout<<"Sum of Complex Numbers are = ";
   problemSolution3.displayResult();
