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

On the far extreme of possible ways to deal with memory leaks is the boehm garbage collector, a conservative mark & sweep collector. Interestingly, this can be used in addition to all the good advice offered in other answers.
