Find the multiples of 3 from the n numbers

Given n numbers , count all the multiples of 3 from the n numbers.

 Method 1: (Brute Force)

1. Read an integer
2. Check if 3 divides the number, increment count if YES
3. Finally, Print the count

Implementation:

#include <stdio.h>
int main()
{
    long int N,i,c=0;
    scanf("%ld",&N);
    while(N--)
    {
            scanf("%ld",&i);
            if(i%3==0)
            c++;
    }
    printf("%ld",c);
    return 0;

}
