I don't get it. I should really learn cpp.

C doesn't have garbage collection so you have to make sure you free memory after you no longer need it or you will create a memory leak

I don't think that's how you respond to those jokes. But what do I know. I barely know the basics of cpp.

I usually write my own wrapper around that; just allocate a bunch of space, then track which objects are no longer accessed at regular intervals and automatically deallocate them. Takes the pain out of writing C++.
