Find sum and average of n elements

Given 'N' elements, find the sum and average of 'N' elements and print them.


Implementation:
#include <stdio.h>
#include <stdlib.h>

/* Array Size */
#define MAX 100000

int main(void) {
 
 /* Sum is initialized to 0 to get rid of garbage values getting intialized*/
 int a[MAX],i,n,sum=0,average;
 
 /* Get the number of elements of the array */
 scanf("%d",&n);
 
 /* Get the elements of the array */
 for(i=0;i<n;i++)
 {
  scanf("%d",(a+i));
  
  /* Calculate the sum of the elements of the array while getting input from the user */
  sum+=*(a+i);
 }
 
 /* Calculate the average of the array */
 average=sum/n;
 
 printf("sum of elements is %d",sum);
 
 printf("average of elements is %d",average);
 return 0;
}
