用C++编写简单的赛车游戏代码

如果你在处理视觉问题，编写游戏需要一些扎实的编程技巧，以及对一些API的强烈掌握，如和。对于C++程序员来说，有一些游戏引擎可以让这个过程变得简单明了。

必要的头文件

dos.h是一个C语言头文件。这个库包括处理中断、发出声音、处理日期和时间等的程序。它是独有的，与 C 等编译器一起发挥作用。

当头文件被用来访问 API方法时，用户使用内置功能会更简单。如果内置功能被利用或包含在主文件中，则在源代码中使用可执行文件。库和或等库中使用的函数被专门包含在头文件中。它使用了各种组件，除了宏的功能外，还能对库中的项目进行修改、扩展和替换。能够在内核中包含C库函数的字符串函数利用。
