C++ keyword to dynamically allocate memory and returning a pointer to this memory location. If the allocation of memory fails, std::bad_alloc is thrown and a pointer to null is returned.
When the pointer is no longer needed, delete must be called.
- Avoid 'naked' new and delete [4,5]
- Prefer the use of smart pointers over the use of plain pointers [1-3].
- Use smart pointers to avoid forgetting to delete objects created using new [6]
