#include<conio.h>

class complex {

//declarare three variables

  int variable_1, variable_2, c;

public:

  complex() {

  }

   

   //A function to get value from the user

  void getvalue() {

    cout << "Enter the Two Numbers:";

    cin >> variable_1>>variable_2;

  }

  void operator++() {

    variable_1 = ++variable_1;

    variable_2 = ++variable_2;

  }

  void operator--() {

    variable_1 = --variable_1;

    variable_2 = --variable_2;

  }

 //Definition of a method for dispaly/ show

  void display() {

    cout << variable_1 << "+\t" << variable_2 << "i" << endl;

  }

};

//definition of the main method

void main() {

  clrscr();

  complex my_object;

  my_object.getvalue();

  my_object++;

  cout << "Increment Complex Number\n";

  my_object.display();

  my_object--;

  cout << "Decrement Complex Number\n";

  my_object.display();

  getch();

  return 0;

}
