Write a c program to reverse an array elements using D.M.A.



#include<stdio.h>
#include<conio.h>
  void main()
{
  int *ip,n,i;
  int max=0;
  clrscr();
  printf("\nEnter the limit: ");
  scanf("%d",&n);
  ip=(int*)malloc(n*sizeof(int));
  printf("\nEnter the elements:\n");
  for(i=0;i<n;i++)
{
  scanf("%d",&ip[i]);
}
  printf("\nEntered elements are:\n");
  for(i=0;i<n;i++)
{
  printf("\n%d",ip[i]);
  printf("\n");
}
  printf("\nReverse array is:");
  for(i=n-1;i>=0;i--)
{
  printf("\n%d",ip[i]);
}
  getch();
}

OUTPUT:

Enter the limit: 4

Enter the elements:
1
2
3
4

Entered elements are:1 2 3 4
