This article introduces how to analyze the C++ stack in C++. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

If you want to learn C++ 's C++ stack well, you must understand what the C++ stack is. Therefore, the C++ stack is a data structure in which data items are arranged in order. Data items can only be inserted and deleted at one end (called top), which is divided into two parts: the stack and the stack.

In C++, memory is divided into five areas, namely, heap, stack, free storage, global / static storage, and constant storage. Stacks are the storage areas of variables that are allocated by the compiler when needed and automatically clear when not needed. The variables inside are usually local variables, function parameters, and so on.

Heap, that is, those blocks of memory allocated by new, their release compiler does not control, and is controlled by our application. Generally, a new corresponds to a delete. If the programmer does not release it, the operating system will automatically recycle it after the program ends. Free storage, those blocks of memory allocated by malloc, etc., is very similar to the heap, but it ends its own life with free.

The global / static storage area, global variables and static variables are allocated to the same memory. In the previous C++ stack, global variables were divided into initialized and uninitialized. There is no such distinction in C++. They share the same memory area. Constant storage area, which is a special storage area, in which constants are stored and are not allowed to be modified (of course, you can also modify them by improper means, and there are many ways)

Windows services are designed for applications that need to run in the background and for tasks that do not have user interaction. To learn the basics of this console application, C (not C++) is the * choice. This article will establish and implement a simple service program.

Its function is to query the amount of physical memory available in the system, and then write the results to a text file. *, you can write your own Windows service with what you have learned. When I wrote * NT services, I went to MSDN for examples. There I found an article written by Nigel Thompson: "Creating a Simple Win32 Service in C++", with an example of C++.

Although this article explains the service development process well, I still feel that I lack the important information I need. I want to understand what framework, what function to call, and when, but C++ doesn't make it much easier for me.

The object-oriented method is convenient, but because the underlying Win32 function calls are encapsulated by classes, it is not conducive to learning the basic knowledge of service programs. This is why I think C is more suitable for writing primary service programs or services that implement simple background tasks. After you have a full and thorough understanding of the service program, you can write it easily with the C++ stack.

When I leave my old job and have to transfer my knowledge to another person, it is very easy to use the examples I wrote in C to explain what NT services are all about. A service is a console program that runs in the background and implements tasks that do not require user interaction. The Windows NT/2000/XP operating system provides special support for service programs.

People can use the service control panel to configure the installed service program, that is, the Windows 2000/XP control panel | the "service" in the administrative tool (or enter services.msc / s services.msc-translator in the "start | run" dialog box). You can configure the service to start automatically when the operating system starts, so that you don't have to start the service manually every time you restart the system.

On how to analyze the C++ stack in C++ to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
