C++ idiom to avoid memory leaks?

Question

In the following code, there is a memory leak if Info::addPart1() is called multiple times by accident:

typedef struct
{
}part1;

typedef struct
{
}         


        

Answer 1

You should read about the smart pointer idiom and about RAII. I suggest taking a look into the new technical report (TR1).
Take a good look here and here.
Also take a look at boost's smart pointers.
I recommend loki-lib's SmartPtr or StrongPtr classes.
