c++对文件操作的支持

#include <stdio.h>
#include <iostream>
#include <fstream>
using namespace std;
void main()
{       int a,b;
char c;
ofstream fout("test.txt");
fout<<" "<<0<<" "<<1<<" "<<4<<endl;
fout<<" "<<3<<" "<<4<<" "<<‘d‘<<endl;
ifstream fin("test.txt");
while (!fin.eof())
{
    fin>>a>>b>>c;
    cout<<a<<" "<<b<<" "<<c<<endl;
}
cin>>a;
}
