Is there a way to find the number of elements in an array?

Here's a simple question that I don't know the answer to. I hope someone knows a trick or two.

Say you have two arrays and you want to make a single function to print the out the elements. One is size 2 and one is size 3 let's say. Is there a way to read the number of elements in an array so that you don't print out 3 elements if you're printing the array with 2 elements?

Or you could always do something odd like use the first element of the array to hold the total number of elements in the array.

Code:

char array[100] = {100};

Why you'd want to do this is beyond me, but you could.

would NELEM(x) also work for arrays of pointers?
