Operator Overloading.

Write a C++ program to add two complex numbers using binary operator overloading.

Program Algorithm:

Step 1: Include the header files

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.

Program Code in C++:

#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();

}

Program Output:

Enter the value of Complex Numbers a, b

7 8

Enter the value of Complex Numbers a, b

5 2

Input Values

7 + 8i

5 + 2i

Result

12 + 10i

2 + 6i
