头文件和源文件的问题，老是出现这个问题，请求大牛帮助
头文件 名称stock
#ifndef STOCK_H_
#define STOCK_H_
class Stock
{
private:
char company;
int shares;
double share_val;
double total_val;
void set_tot(){total_val=shares*share_val;}

void buy(int num,double price);
void sell(int num,double price);
void update(double price);

客户文件 usestock1

stock1=Stock("nifty foods",10,50.0);
cout<<"revised stock1:\n";
stock1,show();
cout<<"done\n";
return 0;
}
编译时为什么老是提示fatal error C1083: 无法打开包括文件:“stock.h”: No such file or directory
[解决办法]
不应该啊，应该没问题啊，是不是打错字，或者stock.h放到其他地方去了！
[解决办法]
主程序和头文件没放在同一个文件夹里吧，主程序加载头文件默认是从它自己所在路径开始搜索的，如果头文件没在同一个文件夹就找不到了。
