Operator Overloading.

Write a C++ program to find the complex numbers using unary 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 increment the values

Step 6: Define the function operator - -to decrement the values.

Step 7: Define the display function.

Step 8: Declare the class object.

Step 9: Call the function getvalue

Step 10: Call the function operator ++() by incrementing the class object and call the function display.

Step 11: Call the function operator - -() by decrementing the class object and call the function display.

Program Code in C++:

#include<iostream.h>

#include<conio.h>

class complex

{

int a,b,c;

public:

complex(){}

void getvalue()

{

cout<<"Enter the Two Numbers:";

cin>>a>>b;

}

void operator++()

{

a=++a;

b=++b;

}

void operator--()

{

a=--a;

b=--b;

}

void display()

{

cout<<a<<"+\t"<<b<<"i"<<endl;

}

};

void main()

{

clrscr();

complex obj;

obj.getvalue();

obj++;

cout<<"Increment Complex Number\n";

obj.display();

obj--;

cout<<"Decrement Complex Number\n";

obj.display();

getch();

}

Program Output:

Enter the two numbers: 3 6

Increment Complex Number

4 + 7i

Decrement Complex Number

3 + 6i
