Question

c++getline读取文件

求高手解答

读取文件DATA.TXT，
文件内容为
Code, Item name, Description, Price (Ex GST), GST
0001, Fish hook, Useful for catching fish, 0.5, 1
0110, Metronome, A device for keeping musical time, 49, 1
1234, Basil, Bunch of basil, 2.5, 0
0002, Bread, Essene Sprouted Bread, 5.2, 0
1000, Blah, Not something you'd buy, 12.4, 1

我做的是
#include<iostream>
#include<string>
#include<fstream>
#include<iomanip>

using namespace std;
typedef struct{
string id;
string name;
string dec;
double price;
double gst;
}abc;

int main()
{
abc s[6];
int i;
ifstream fin;
fin.open("data.txt");
if(fin.is_open()==false)cout<<"error"<<endl;
else
fin.ignore(100,'\n');

for(i=1;i<=6;i++){

getline(fin,s[i].id,',');
getline(fin,s[i].name,',');
getline(fin,s[i].dec,',');
fin>>s[i].price;
fin>>s[i].gst;

cout<<s[i].id<<" - "<<s[i].name<<"("<<s[i].dec<<"): $"<<s[i].price<<endl;

};

fin.close();

return 0;

}

只COUT了第一行，我知道是光标错误，可是自己不会改，求高手帮忙～～
显示成这个样子
0001 - Fish hook (Useful for catching fish): $0.50*
0110 - Metronome (A device for keeping musical time): $49.00*
1234 - Basil (Bunch of basil): $2.50
。。。

谢谢～
