From Chapter 7th of C ++ Object-Oriented Programming (15th) 1. The base class is a virtual function, and the derived class is a virtual function automatically (whether or not there is a virtual keyword), but a good code style: Add virtual keywords 2.

  The specific requirement is that at a certain point in time, only n threads are executing concurrently. If there are redundant threads, the queue will wait ~ It's really a waste of effort ~ Finally, it was overcome by me. I will introduce the

Like java, writing a multi-threaded application in C # is very simple. This chapter describes how to develop multi-threaded programs in C. In. net, threads are defined by the system. Threading namespace. Therefore, you must include this

Every program shoshould begin with a comment that describes the purpose of the program, author, date and time. Use blank lines and space characters to enhance program readability. Omitting the semicolon at the end of a C ++ statement is a syntax

The compiler inserts hidden data called a virtual pointer (vptr) into a class with at least one virtual function. Vptr is a pointer to the virtual function address list. In different compilers, The vptr location is different.   Some compilers (such
