用标准库也许boost分割C++字符串

使用标准库

#include <iostream>
#include <vector>
#include <string>
#include <sstream>
using namespace std;

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)) {
		if (!item.empty()){
			elems.push_back(item);
		}
	}
	return elems;
}

std::vector<std::string> split(const std::string &s, char delim) {
	std::vector<std::string> elems;
	split(s, delim, elems);
	return elems;
}

int main(){
	string s = "string	to	split a";
	vector<string> columns = split(s, '\t');
	for (vector<string>::iterator it = columns.begin(); it != columns.end(); it++){
		cout << *it << endl;
	}
	return 0;
}

使用boost 

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

int main(){
	string s = "string	to	split a";
	vector<string> strs;
	boost::split(strs, s , boost::is_any_of("\t"));
	for (vector<string>::iterator it = strs.begin(); it != strs.end(); it++){
		cout << *it << endl;
	}
	return 0;
}
