Hey /prog/
I never really used C or C++ before, other than when I started learning programming. I want to do something in one of them, (maybe an OS lol) but I'm not very confident about allocating/freeing up memory (I haven't done it before often).
Just to refresh my memory, as long as I use malloc and free with C and new and delete keywords with C++ I'm safe, right? And can I use malloc and free in C++ too?

Also, discuss Objective-C and the Sepplesox I heard about before.

How do I make sure a char* has a 0 somewhere? Should I zero all the elements (I vaguely remember there being a function for doing that), or manually put a zero at the end/at the start?
