Answer:




// Question: Write a program using pointers to swap two integers. *

#include <iostream.h>
#include <conio.h>

void swap_using_pointers(int *, int *);

void main()
{
 clrscr();
 int a,b;
 cout<<"\n\nEnter first  integer : "; 
 cin >> a;
 
 cout<<"\n\nEnter second integer : "; cin>>b;
 
 swap_using_pointers(&a,&b);
 
 cout<<"\n\nNow value of first  integer = "<<a;
 cout<<"\n\nNow value of second integer = "<<b;
 getch();
}

void swap_using_pointers(int *a,int *b)
{
 int temp;
 temp=*a;
 *a=*b;
 *b=temp;
}
