Sum of Array Elements

Given a user defined array the task is to calculate the sum of the elements of the array using pointer.

Example:

Consider an array of size 5.

51736

The sum of all elements will be 5+1+7+3+6 = 22

C
#include <stdio.h>
int main()
{
    int n=0,sum=0;
    printf("Enter the size of array: ");
    scanf("%d",&n);
    int ar[n];
    int *p=ar;
    printf("Enter the array elements:\n");
    for(int i=0;i<n;i++)
    {
        scanf("%d",p);
        p++;
    }
    p=ar;
    for(int i=0;i<n;i++)
    {
        sum=sum+*p;
        p++;
    }
    printf ("Sum of all the elements: %d",sum);
    return 0;
}
