How to check if all numbers in array are divisible by N in C

Answer 1

#include <stdio.h>
#include <stdbool.h>
  
bool is_divisible_by(int arr[], int n, int len) {
	 
	for (int i = 0; i < len; i++)  
            if (arr[i] % n != 0)
				return false;
	return true;
}
int main ()
{
	int arr[] = {4, 8, 12, 16, 20, 24, 28, 32};
	const int n = 4;

	printf("%d\n", is_divisible_by(arr, n, sizeof(arr) / sizeof(int)));
	
	return 0;
}
