(C++ is the successor of the C language. It can carry out procedural programming in C language, object-oriented programming characterized by abstract data types, object-oriented programming characterized by inheritance and polymorphism. design. While C++ is good at object-oriented programming, it can also do procedural-based programming, so C++ is suitable for the size of the problem. C++ not only has the practical characteristics of efficient computer operation, but also devotes itself to improving the programming quality of large programs and the problem description ability of programming language.)
