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

Use a smart pointer such as boost:shared_ptr , boost:scoped_ptr is recommended to manage the raw pointer. auto_ptr is tricky to work with, you need pay attention to that.
