Creating Calculator Program Using Cpp

Implement a class Complex which represents the Complex Number data type. Implement the following operations:
1. Constructor (including a default constructor which creates the complex number 0+0i).
2. Overloaded operator+ to add two complex numbers.
3. Overloaded operator* to multiply two complex numbers.
4. Overloaded << and >> to print and read Complex Numbers.


We are using g++ compiler and terminal to compile the code and ubuntu OS.

 PROGRAM:


#include<iostream>
using namespace std;
int main()
{
 PROGRAM:
   int a,b,c;
   char op,d;
   do
   {
   cout<<"Enter the first number:";
   cin>>a;
   cout<<"Enter the second number:";
   cin>>b;
   cout<<"Enter operator +,-,*,/:";
   cin>>op;
      switch(op)
      {
       case'+':
         c=a+b;
         cout<<"Addition:"<<a<<"+"<<b<<"="<<c;
         break;
       case'-':
         c=a-b;
         cout<<"Substraction:"<<a<<"-"<<b<<"="<<c;
         break;
       case'*':
         c=a*b;
         cout<<"Multiplication:"<<a<<"*"<<b<<"="<<c;
         break;
       case'/':
         c=a/b;
         cout<<"Divition:"<<a<<"/"<<b<<"="<<c;
         break;
       default:
         cout<<"Enter Valid operator";
       }
         cout<<"\nDo you wan to continue(Y/N):";
         cin>>d;
     }while(d=='Y'||d=='Y');
return 0;
}
