First, install VS2022

Tips: when selecting installation information, check "General Windows platform Development" when learning the C language, and "Desktop Development using C++", considering that you will use it later. It is worth mentioning that after the installation is complete, this installation information can also be modified in the subsequent learning process.

Second, create a project test program

Click the top status bar to debug-start execution (do not debug) and run the program.

Success!

Third, encounter problems

In VS2022, there was an error compiling with the scanf function: error C4996: 'scanf': This function or variable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _ CRT_SECURE_NO_WARNINGS. See online help for details.

IV. Solutions

Add macro definition to cancel safe security, or use scanf_s

Add macros to define ways to remove safe security:

Add at the beginning of the code:

# define _ CRT_SECURE_NO_WARNINGS

As shown in the following figure:

But it seems a little troublesome to add a macro definition every time, and there is a good way:

Find a file called "newc++file.cpp" in your vs2022 installation directory, open it as an administrator, add # define _ CRT_SECURE_NO_WARNINGS, and save it. This code will exist when you create the source file later, so as not to add it again.
