strtok分离字符串

     strtok在分离有规律分隔符的字符串的时候，用处很方便，不过千万要记得_CRTIMP char * __cdecl strtok(char *, const char *)第一个参数不能指向存在于

静态存储空间的字符串，否则程序会崩溃异常。这个也是函数的不足之处。以下是简单实现

// StrTok.cpp : Defines the entry point for the console application.
//

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

int SplitString(char* SourcesStr,const char* seps,vector<char*> &strVec)
{
  
    char* element;
    int i=0;

    if(strlen(SourcesStr)==0)
    {
       return -1;
    }

    if (strlen(seps)==0)
   {
        strVec.push_back(SourcesStr);  
        return 0;
   }

    cout << SourcesStr << endl;
    cout << seps << endl;

    element = strtok(SourcesStr, seps);
    while (element != NULL)
   {  
        strVec.push_back(element);
        element = strtok( NULL, seps);   
    }

    return 0;
}

 

int main(int argc, char* argv[])
{

  
    vector<char*> vec;
    char str[]="abc,bac,aaa,bbb"; //strtok不能指向静态区的字符串
    int ret = SplitString(str,",",vec); //调用SplitString("abc,bac,aaa,bbb",",",vec);会发生异常
   
    if (ret == -1)
    {
          return 0; 
    }

    vector<char*>::iterator iter = vec.begin();
    for (;iter != vec.end();++iter)
    {
         cout << *iter << endl;
    }

    return 0;
}
