split字符串以多字符串切割

split字符串以多字符串切割

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

std::vector<std::string> split(const std::string& str, const std::string& delim)
{
    std::vector<std::string> res;
    if ("" == str)
        return res;
    //先将要切割的字符串从string类型转换为char*类型
    char * strs = new char[str.length() + 1];
    strcpy(strs, str.c_str());

    char * d = new char[delim.length() + 1];
    strcpy(d, delim.c_str());

    char *p = strtok(strs, d);
    while (p) {
        std::string s = p; //分割得到的字符串转换为string类型
        res.push_back(s); //存入结果数组
        p = strtok(NULL, d);
    }

    return res;
}

int main()
{
	string s = "ewa+bqwe,ccsd,dcv,e+fas";
	vector<string> v;
	v = split(s,"+,"); //可按多个字符来分隔;
	for(vector<string>::size_type i = 0; i != v.size(); ++i)
	   cout << v[i] << " ";
	cout << endl;
}

输出结果

ewa bqwe ccsd dcv e fas
