How do I find the length of an array?

Question

Is there a way to find how many values an array has? Detecting whether or not I\'ve reached the end of an array would also work.

Answer 1

sizeof(array_name) gives the size of whole array and sizeof(int) gives the size of the data type of every array element.

So dividing the size of the whole array by the size of a single element of the array gives the length of the array.

 int array_name[] = {1, 2, 3, 4, 5, 6};
 int length = sizeof(array_name)/sizeof(int);
