c++字符串char[]数组分割split问题

#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main()
{
    vector<char*> res_split;//存储分割后的字符串
    char *name = "camera 10_2020821_1_23.bmp";
    char image_name[100];
    strcpy(image_name, name);
    const char split[] = "_";
    char* res = strtok(image_name, split);//image_name必须为char[]
    while (res != NULL)
    {
        res_split.push_back(res);
        cout <<res << endl;
        res = strtok(NULL, split);
     }
    cout << res_split.at(2) << endl;
    system("pause");
    return 0;
}

char * strtok (char * str, const char * delimiters);

#include <string>
#include "stdio.h"
int main ()
{
    char str[] ="a,b,c,d*e";
    const char * split = ",";
    char * p;
    p = strtok (str,split);
    while(p!=NULL) {
        printf ("%s\n",p);
        p = strtok(NULL,split);
    } 
    return 0;
}

const char * split = “,”;

const char * split = “,“; //用逗号(,)和星号()对字符串进行分割
