Unmanaged C ++ garbage collection help

Question

I am a .net programmer, without much experience with unmanaged code. I am adding changes and additions to an unmanaged project, and everything works fine. Can you give me some guidance as to which code / objects I need to worry about garbage collection?

TIA

Answer 1

Missing. C ++ has no garbage collector.

Answer 2

In C ++, when allocating memory manually using an operator, newspecifying it frees this memory later (when it is no longer needed) using the operator delete.

/ malloc/?

delete foo;
foo=null;

the next time you can check if it is zero, and otherwise delete them. And the best ... even if you try to remove the null pointer, nothing will happen! :)

Answer 6

Find out if the code uses smart pointers (probably this is the case), smart pointers must destroy the objects themselves when they go out of scope.
