Array length counting anomaly

Question

The count is returning unpredictable results. Sometimes they are right. Sometimes totally weird. Anyone can tell me what is wrong?

#include 
int l         


        

Answer 1

Unlike strings, normal arrays do not terminate with a null byte 0x00. The reason strings use this is because arrays have no concept of length; arrays are merely contiguous pieces of memory, it is up to you to keep track of the length of arrays.
