Write a C++ program to swap the values of a pair of integers using reference variables

#include<iostream.h>
#include<conio.h>
class abc
{
  private:
    int t;
  public:
    void swap(int *a, int *b)
    {
      t=*a;
      *a=*b;
      *b=t;
    }
};
void main()
{
  int a,b;
  clrscr();
abc sa;
  cout<<"Enter the values of A: ";
  cin>>a;
  cout<<"Enter the values of B: ";
  cin>>b;
  sa.swap(&a,&b);
  cout<<"\nValues of A is: "<<a;
  cout<<"\nValues of B is: "<<b;
  getch();
}




OUTPUT

Enter the values of A:32
Enter the values of B:65

Values of A is: 65
Values of B is: 32
