C program to swapping the two numbers using function concept

#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.
