Print number of elements of the array

Given an array, Print number of elements of the array.

For example:

If the array is 
1 2 3 4 5 6

then the number of elements of the array is 6

Implementation:

#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
int main(void) {
 int *a,n,i;
 
 /* Get the number of elements of the array */
 scanf("%d",&n);
 
 /* memory allocation to store n elements */
 a=(int*)malloc(sizeof(int)*n);
 
 /* Get the elements of the array */
 for(i=0;i<n;i++)
 {
  scanf("%d",(a+i));
 }
 
 /* Print the size of the array or number of elements of the array */
 printf("number of elements in the array is %d",n);
 return 0;
}
