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

I personally would suggest (if you are unable to work with specialized functions for whatever reason) to first expand the arrays type compatibility past what you would normally use it as (if you were storing values ≥ 0:

unsigned int x[] -> int x[]

than you would make the array 1 element bigger than you need to make it. For the last element you would put some type that is included in the expanded type specifier but that you wouldn't normally use e.g. using the previous example the last element would be -1. This enables you (by using a for loop) to find the last element of an array.
