Because the operating system we usually use is Windows, and the longest C/C++ compiler in this system is VC++ compiler, so the version commonly used in colleges and universities is VC++6.0.
Let's use VC++6.0 to illustrate the compilation process:
1. Open the snake code in VC++6.0 through the "Open" submenu under the "File" menu.
2. Compile the snake code in VC++6.0 through the "Compile xxxx.xx" submenu under the "Build" menu.
3. Run the snake program in VC++6.0 through the "Execute xxxx.exe" submenu under the "Build" menu.
Attachment: C/C++ snake source code that can run in VC++6 environment (no copyright, write it yourself, welcome to modify and copy it at will).
