If we implement a linked list by ourselves, we will write a lot of code, including the operation of creating, deleting, inserting, and so on. But if we use STL, then the template Library gives us a list of doubly linked lists, which makes it very

Primitive built-in Types:C + + offer the programmer a rich assortment of built-in as well as user defined data types. Following table lists down seven basic C + + data types: TYPE Keyword boole An bool

C + + programming directly supports three programming patterns (programming Paradigms), program model, program data type model (OB), Object-oriented model (OO)　　1, the program model: similar to the C language, with the process-based statement
