源程序其中一个.c文件如下..仿照C语言数据结构课本的程序写的.结果一编译就报错
"microsoft visual studio\vc98\mfc\include\afx.h(15) : fatal error C1189: #error :  MFC requires C++ compilation (use a .cpp suffix)
执行 cl.exe 时出错."
何解???

#include "dcourse.h"
#include "dinfo.h"
#include "dcomm.h"

#include <string.h>

呃。主要是要求用C来写..想找出什么地方用了MFC....然后改回来.=,=
