nul terminating a int array

Question

gcc 4.4.4 c89

I was just experimenting with a int array. And something just came to my mind. Can I nul terminate it. For example, I am using a 0 to nul terminate. Ho

Answer 1

Simply put, \0 is the same as 0, so if you have a zero in your array your code will mistake that for the array's end:

int arr[] = {30, 450, 14, 5, 0, 10, '\0'};
                             ^ this is the end of the array

Edit: note that by "end of the array" I mean the conceptual end of the array as defined by your algorithm, rather than the actual extents of the data laid out in memory by the C programming language.
