Program to interchange two values using pointers(swaping value)

#include<stdio.h>
#include<conio.h>

int main()
{
 // Declaring variable a, b for two values, swap to interchange value
 int a, b, swap;
 
 // Declaring pointer that holds address of two values
 int *c, *d;
 
 // Storing address
 c=&a;
 d=&b;
 
 // Inputing values
 printf("Enter first value a : ");
 scanf("%d",&a);
 
 printf("Enter second value b : ");
 scanf("%d",&b);
 
 // Printing original value
 printf("Original value : a = %d, b = %d\n",a, b);
 
 // Interchanging value
 swap=*c;
 *c=*d;
 *d=swap;
 
 // Printing interchanged value
 printf("Interchanged value : a = %d, b = %d ",a, b);
  
 getch();
 return 0;
