How can I find the number of elements in an array?

Question

I have an int array and I need to find the number of elements in it. I know it has something to do with sizeof but I\'m not sure how to use it exac

Answer 1

i mostly found a easy way to execute the length of array inside a loop just like that

 int array[] = {10, 20, 30, 40};
 int i;
 for (i = 0; i < array[i]; i++) {
    printf("%d\n", array[i]);
 }
