Operator overloading.

Write a C++ program for using operator overloading.

Algorithm:

Step 1: Start the program.

Step 2: Create a class called complex.

Step 3: Initialize the complex data members inside the constructor.

Step 4: Define the operator+ using operator overloading.

Step 5: Create an object and call the member functions.

Step 6: Print the output.

Step 7: Stop the program.

Program Code:

#include<iostream.h>

#include<conio.h>

class complex

{

float x;

float y;

public:

complex()

{

}

complex(float real,float imag)

{

x=real;

y=imag;

}

complex operator+(complex);

void display();

};

complex complex ::operator+(complex c)

{

complex temp;

temp.x=x+c.x;

temp.y=y+c.y;

return(temp);

}

void complex::display()

{

cout<<x<<"+j"<<y<<"\n";

}

void main()

{

complex c1,c2,c3;

c1=complex(2.5,3.5);

c2=complex(1.6,2.7);

c3=c1+c2;

cout<<"c1=";

c1.display();

cout<<"c2=";

c2.display();

cout<<"c3=";

c3.display();

return 0;

}

Output:

c1=2.5+j3.5

c2=1.6+j2.7

c3=4.1+j6.2
