要求将字符串 "mallid=310103123456\ntermno=139654785231\norder=00003995\ngcode=0000130\npaydate=20051031\nname=\ncardno=5248000262355365\nlimit=0804\nprice=2210" 以\n为分界符，提取出所有的字符串。
刚好最近在看STL，感觉可以用stream来解决，于是就小试了一下。结果还真令人满意

。

#include <iostream>

#include <sstream>

#include <vector>

#include <algorithm>

#include <ITERATOR>

#define INPUT_STRING "mallid=310103123456\ntermno=139654785231\norder=00003995\ngcode=0000130\npaydate=20051031\nname=\ncardno=5248000262355365\nlimit=0804\nprice=2210"

typedef std::vector<std::string> strvec;

int _tmain(int argc, _TCHAR* argv[])

{

using namespace std;

istringstream iss(INPUT_STRING);

strvec strList;

string strTemp;

while(iss >> strTemp)

{

strList.push_back(strTemp);

}

// out put the result

copy(strList.begin(), strList.end(), ostream_iterator<string>(cout, "\n"));

return 0;

}
