OverviewThe thread function has either no parameters, or only one object parameter, and there is no return value, which greatly reduces the flexibility of the program, but what we want is to be able to use parameters and return values as normal

Before we discuss global variables, we need to understand a few basic concepts:1. Compilation unit (module):In the IDE development tools of the big line of the today, some of the concepts of compilation is no longer clear, many programmers are most

In C #, if you want the length of an array and the number of elements to change as the program runs, you can use the ArrayList class, which is an array that dynamically increases or decreases the members.The common properties and methods of

We all know that the member functions of the classes in C + + provide the this pointer by default, and in non-static member functions, when you call a function, the compiler will "automatically" help you add the this pointer to the function
