在编程序时看到一个#include和#include请问他们是做什么的呢.在VC编译器里没有吗?

我在编写程序时有一次看到俩个库头文件<DOS.H>和<BIOS.H>它们在VC编译器里不自带吗.如果想使用应该怎么办那!!!!

7 个解决方案

#1

那是古代的dos操作系统所调用的东西，什么dir,cls,time七七八八的，那个bios.h,我也没用过，估计是人如其名。因为是古代的东西，所以现代的vc都不带了。（猜测，希望高手解释）
ps：这里有长沙的在河西读大学的吗？

#2

我学的一本c++上也有dos.h,在vc6.0和最新的devc++都不支持。

#3

那都是DOS程序设计的知识,现在是WINDOWS时代,都用#include<windows.h>

#4

嘿嘿，长知识了。

#5

我在一个叫c700的文件夹里找到bios.h

在vc6.0里面有dos.h
