C/C++ ifstream之eof()

参考来自：http://blog.youkuaiyun.com/rebel_321/article/details/4927464

程序实测可用：

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
string str;
ifstream fin("D:\\1.txt"/*, ios::binary*/);
if (fin.peek() == EOF)
{
cout << "file is empty." << endl;
return 0;
}


while (!fin.eof())
{
fin >> str;
cout << str<<' ' ;
}
system("pause");
return 0;
}
