Question

关于vc++6.0的问题

我是初学的，想问下这个错误是怎么回事儿，还有，有时候出现cl.exe错误也不知道怎么解觉

Answer 1

《C++程序设计原理与实践》？
#include"std_lib_facilities.h"这个头文件在他的主页上有源文件,需要你自己新建一个这个名字的头文件,将内容拷贝进去才可以
对于你这个程序，直接改成
#include<iostream.h>就可以运行通过。
附：std_lib_facilities.h源码
/* simple "Programming: Principles and Practice using C++" course header to be used for the first few weeks. It provides the most common standard headers (in the global namespace) and minimal exception/error support. Students: please don't try to understand the details of headers just yet. All will be explained. This header is primarily used so that you don't have to understand every concept all at once.
