實現c++的string的split功能

今天寫程序，遇到了一個要實現string.split()這個的一個函數。python里面有,qt里面有，c++里面沒有。照着網上抄了一個，放在這里。有需要的時候直接拽過去用，否則老是寫了小例子就扔，用的時候沒有，也是個麻煩事

例如 “aa*bb*cc” 會存儲成vector<string> "aa" "bb" "cc"

// temp1.cpp : 定義控制台應用程序的入口點。

#include "stdafx.h"
#include <iostream>
#include <stdio.h>
#include <string>
#include <vector>
using namespace std;

 
int _tmain(int argc, _TCHAR* argv[])
{
    char a[] = "abc*123*xyz";  //目標是解析成 abc  123 xyz 然后存儲在下面的變量 vector<string>中
    string strArry = a;
    vector<string> strArryList;


    size_t last = 0;
    size_t index = strArry.find_first_of("*",last);  //找到last坐標后面的第一個*
    while( index != std::string::npos )//找到一個推進vector一個,一直到找到了最后
    {
        strArryList.push_back( strArry.substr(last, index-last));
        last = index +1;
        index = strArry.find_first_of("*",last);
    }
    if(index - last > 0) //記得把最后一個推進去.這里是"xyz"
    {
        strArryList.push_back( strArry.substr(last, index-last));
    }


    for(int i = 0; i < strArryList.size(); i++)
    std::cout<<strArryList[i]<<std::endl;

    getchar();
    return 0;
}

 下面是又寫的一個split函數的代碼

#include <iostream>
#include <string>
#include <vector>

using namespace std;
// spCharacter [IN] : 分隔符
// objString [IN] : 要分解的字符串
// stringVector [OUT] : 分解了的字符串
bool splitString(char spCharacter, const string& objString, vector<string>& stringVector)
{
    if (objString.length() == 0)
    {
        return true;
    }

    size_t posBegin = 0;
    size_t posEnd = 0;
    bool lastObjStore = true;

    while (posEnd != string::npos)
    {
        posBegin = posEnd;
        posEnd = objString.find(spCharacter, posBegin);

        if (posBegin == posEnd)
        {
            posEnd += 1;
            continue;
        }

        if (posEnd == string::npos)
        {
            stringVector.push_back( objString.substr(posBegin, objString.length()-posBegin) );
            break;
        }
        
        stringVector.push_back( objString.substr( posBegin, posEnd - posBegin) );
        posEnd += 1;    
    }
    return true;
}
int main(int argc, char** argv)
{
    vector<string> paths;
    paths.push_back("abcde");
    paths.push_back("aaar/");    
    paths.push_back("aaar//");    
    paths.push_back("aaar/bbb");    
    paths.push_back("aaar/c/bbb");    
    paths.push_back("aaar//bbb");    
    paths.push_back("/aar");    
    paths.push_back("/");    
    paths.push_back("");    
    
    for (auto iter = paths.begin(); iter != paths.end(); iter++)
    {
        vector<string> temp;
        splitString('/', *iter, temp);

        cout<<"--------begin------"<<endl;
        cout<<"the source string : ["<<*iter<<"]"<<endl;
        cout<<"-------------------"<<endl;
        for (auto iterSplit = temp.begin(); iterSplit != temp.end(); iterSplit++)
        {
            cout<<*iterSplit<<endl;
        }
        cout<<"--------end------"<<endl<<endl;;
    }

    return 0;
}
