#include<stdio.h>

#include<conio.h>

void swap(int,int);

void main()

{

  int x,y;

  clrscr();

  printf("enter the values of x and y:\n");

  scanf("%d%d",&x,&y);

  printf("\nbefore swapping values are:x=%d,y=%d",x,y);

  swap(x,y);

  getch();

  }

  void swap(int m,int n)

  {

    int temp;

    temp=m;

    m=n;

    n=temp;

    printf("\nafter swapping values are:m=%d,n=%d",m,n);

    getch();

   }

OUTPUT :

enter the values of x and y:

2 

3

before swapping values are:x=2,y=3

after swapping values are:m=3,n=2

Process finished.
