Splitting strings in C++

this works nicely for me :), it puts the results in elems . delim can be any char .

std::vector<std::string> &split(const std::string &s, char delim, std::vector<std::string> &elems) {
    std::stringstream ss(s);
    std::string item;
    while(std::getline(ss, item, delim)) {
        elems.push_back(item);
    }
    return elems;
}

有了这个包含Boost的Mingw发行版：

#include <iostream>
#include <string>
#include <vector>
#include <iterator>
#include <ostream>
#include <algorithm>
#include <boost/algorithm/string.hpp>
using namespace std;
using namespace boost;

int main() {
    vector<string> v;
    split(v, "1=2&3=4&5=6", is_any_of("=&"));
    copy(v.begin(), v.end(), ostream_iterator<string>(cout, "n"));
}

Try using stringstream:

std::string   line("A line of tokens");
std::stringstream lineStream(line);

std::string token;
while(lineStream >> token)
{
}
