The main content of this article is "how to build C++ development environment", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn how to build a C++ development environment.

1. let's first look at the benefits of inline functions: from a user's point of view, inline functions look the same as ordinary functions, they can have parameters and return values, or they can have their own scope. however, it does not introduce the burden of general function calls. In addition, it can be safer and easier to debug than macros.

Of course, you should be aware that inline specifier is only a recommendation to the compiler, and the compiler has the right to ignore this recommendation. So how does the compiler decide whether a function is inlined or not? In general, key factors include the size of the function body, whether any local objects are declared, the complexity of the function, and so on.

2. What happens if a function is declared as inline but is not inlined? In theory, when the compiler refuses to inline a function, that function will be treated like a normal function, but there will be other problems. For example, the following code:

/ / filename Time.h # include # include using namespace std; class Time {public: inline void Show () {for (int I = 0; I
