STL provides a number of generic containers, such as vector,list and map. Programmers use these containers only to care about when to plug objects into the container, not to care about how to manage memory, how much memory to use, these STL

1. The difference between a reference and a pointer1) When the reference is created, it needs to be initialized, and the pointer can wait until it is initialized at any time.2) The reference cannot point to null, and the pointer can point to NULL3)

Pointer type coercion is very common in kernel designs, where two very interesting uses are recorded:1, the operation of the address. Any virtual address is represented as void *va = (void *), * (VA + 1) ==101, which represents the next virtual

Templates are the basis for generic programming in C + +. A template is a blueprint or formula that creates a class or function. When using generic types such as vectors or generic functions such as find, we provide enough information to convert the
