C ++ Memory Problems record

C ++ memory problems that may come up roughly there are so few ways:

1. Buffer overflow (buffer overrun).

   Use vector / String buffer to manage automatically the length of a buffer in mind, and modify the buffer member functions, rather than a raw pointer.

2. Dangling pointers, wild pointers.

   用shared_ptr/weak_ptr

3. Repeat release (delete twice).

   With scoped_ptr, released only once when the object destruction.

4. Memory leaks (memory leak).

   With scoped_ptr, the object is automatically released when the destructor.

5. Unpaired new delete.

   Try to avoid their own new, using the vector.

6. Memory chips (memory fragmentation).
