The character set of the C language The C language character set consists of letters, numbers, spaces, punctuation, and special characters. 1. Letter Small Letter A~z Total 26 Capital Letter A~z Total 26 2. Digital 0~9 a total of 10 3. Blank

When we use software, we often see many dynamic connection libraries. The dynamic Connection Library has its own advantages, such as memory saving and multi-language support. In addition, when the function in the DLL changes, the called function

1. OverviewThe Aho-corasick automatic machine algorithm (AC automatic machine) was developed by Bell Laboratory in 1975. The algorithm uses finite automatic machines to skillfully convert character comparison to state transfer. This algorithm has

Programmers who use C/C ++ to develop software often encounter this problem: sometimes there is no problem in program compilation, but the function is always reported when the link is used (the classic LNK 2001 error ), sometimes there are no errors

The role of a virtual function is to allow you to redefine a function with the same name as the base class in a derived class, and you can access functions with the same name in the base class or the derived class through a base class pointer or
