C Program Sum of Array Using Pointers

#include <stdio.h>
int main()
{
   int a[50], i,n, sum=0;
   int *ptr;
   printf("\n Write a C Program To:");
   printf("\n Input elements and Find Sum in");
   printf("\n Array Using Pointers in C:"); 
   printf("\n ------------------------------------\n");    
   
   printf(" Enter the number of elements of the array:");
   scanf("%d",&n);
   
   ptr = a;
   
   for(i=0;i<n;i++)
      {
	  printf(" Enter Element a[%d] : ",i);
	  scanf("%d",ptr++);
	  }
   
   ptr = a;
   for(i=0;i<n;i++)
      {
	  sum = sum + *ptr++;
	  }
	printf(" Sum of Array Elements using Pointer=%d",sum); 
	 
	return 0;
}
