关于Visual c++ 6.0的小疑问，求助！！！

谓我心忧

//talkback.c--一个能为你提供一切信息的对话程序。
#include <stdio.h>
#include <string>
#define DENSITY

int main(void)
{
float weight, volume;
int size, letters;
char name[40];

printf("HI What's your first name: \n");
scanf("%s", &name);
printf("%s, what's you weight in pounds: \n", name);
scanf("%f", &weight);
size = sizeof name;
letters = strlen(name);
volume = weight/DENSITY;
printf("well, %s, your volume is %2.2f cubic feet.\n", name, volume);
printf("Also, your first name has %d letter,\n", letters);
printf("and we have %d bytes to store it in.\n", size);
return (0);
}

代码如上，自觉没有任何问题，但是编译之后，出现了一个error：
c:\program files\microsoft visual studio\vc98\include\eh.h(32) : fatal error C1189: #error :  "eh.h is only for C++!"
此时选中这个error之后，突然所有的源代码都变了。

我都不认识了，这到底是怎么回事？求大神解答啊，上网百度了一下那个error，说是什么不是c++文件，但我确实是按照小甲鱼教的方式创建的啊，怎么突然就出现问题了呢，郁闷，跪求答案啊~~~~~~~~

#define DENSITY
问题出在这里，这里后面要有值好比#define DENSITY 1
这样就行了
