头文件里面还有个函数 的实现？？？

头文件里面都是函数的声明  实现放在.cpp文件里面

再用的时候加上#include"XXX.h"

我也没见过#include "XXX.cpp"的

不过可以把你写的函数放到标准名空间里面去  然后去用 using namespace std;

去调用里面的函数

参考书上 stdio.h 的写法，应该有的，是一种结构体的那种，看着办吧！

下面是VC中stdio.h里面的内容，参考下怎么写吧：

好像编译不过

BS直接CP代码的人

菜鸟路过了一下。。

其实，我觉得吧，复制别人代码到VC里运行不通过的，可以自己查错误，找出错误的地方修改好。这样对学习也不错啊

。。

这个代码把我看晕了，
