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

You cannot count arrays like that. Only strings are null terminated. If you want that to work reliably, you will need to add an additional element to your array that contains '\0'. But be sure to remember to take into account that your length will no be one larger then the true length because of that '\0'
