c++ 格式读取文件

本文转自http://bbs.csdn.net/topics/390294887

文件每行如下：

2 "Anthony  van Raan" 9
把第一列存入到整数中，中间存入到字符串数组中，最后存入到一个整数中
ifstream fin("data.txt");
string s;  
getline(fin,s);
之后如何将s分开

# include <iostream># include <sstream>using namespace std;int main(){    string s = "2 \"Anthony van Raan\" 9";    const char * digits = "0123456789";    string::iterator it1 = s.begin();    string::iterator it2 = s.begin() + s.find_first_not_of(digits);    string::iterator it3 = s.begin() + s.find_last_not_of(digits) + 1;    string::iterator it4 = s.end();    string s1(it1, it2);    string s2(it2, it3);    string s3(it3, it4);    int first, last;    char str[BUFSIZ];    stringstream(s1) >> first;    strcpy(str, s2.c_str());    stringstream(s3) >> last;    cout << first << endl         << str << endl         << last << endl;    return 0;}
