Simple Program for Binary Operator Overloading Using C++ Programming

To write a program to add two complex numbers using binary operator overloading.

ALGORITHM:

Step 1: Start the program.

Step 2: Declare the class.
Step 3: Declare the variables and its member function.
Step 4: Using the function getvalue() to get the two numbers.
Step 5: Define the function operator +() to add two complex numbers.
Step 6: Define the function operator –()to subtract two complex numbers.
Step 7: Define the display function.
Step 8: Declare the class objects obj1,obj2 and result.
Step 9: Call the function getvalue using obj1 and obj2
Step 10: Calculate the value for the object result by calling the function operator + and     operator -.
Step 11: Call the display function using obj1 and obj2 and result.
Step 12: Return the values.
Step 13: Stop the program.

PROGRAM:

#include<iostream.h>

#include<conio.h>

class complex

 {

    int a,b;

     public:

      void getvalue()

        {

          cout<<"Enter the value of Complex Numbers a,b:";

          cin>>a>>b;

        }

          complex operator+(complex ob)

           {

              complex t;

              t.a=a+ob.a;

              t.b=b+ob.b;

              return(t);

            }

              complex operator-(complex ob)

              {

                 complex t;

                 t.a=a-ob.a;

                 t.b=b-ob.b;

                 return(t);

              }

                void display()

              {

                            cout<<a<<"+"<<b<<"i"<<"\n";

              }

 };

    void main()

     {

       clrscr();

       complex obj1,obj2,result,result1;

       obj1.getvalue();

       obj2.getvalue();

       result = obj1+obj2;

       result1=obj1-obj2;

       cout<<"Input Values:\n";

       obj1.display();

       obj2.display();

  

       cout<<"Result:";

       result.display();

       result1.display();

  

       getch();

     }

Output:

Enter the value of Complex Numbers a, b
4                  5

Enter the value of Complex Numbers a, b
2                  2

Input Values
4 + 5i
2 + 2i

Result
6 +   7i
2 +   3i
