I have to separate the elements in this file from commas and transfer them to a two dimensional matrix. First i read the file and equaled a value. Then i converted to string value from char array. Then i seperated from commans with strtok function. Then i created a for loop. But its not working.

#include <iostream>
#include <fstream>
#include <cstring>
#include <bits/stdc++.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */
using namespace std;

void ReadFileFunc(){
    ifstream readFile("kisiler.txt"); 
    
    string cumle = "";
    string kelime = "";
    string word = "";
    while(readFile >> cumle){
        
        kelime += cumle;
        kelime+="\n";
        //cout<<"Aktarildi"<<endl;
    }
int n = kelime.length();

char kelime_array[n+1];
strcpy(kelime_array,kelime.c_str());
for(int i = 0; i<n;i++){
    cout << kelime_array[i];
}

//cout << kelime<<"\n \n";
cout << endl;

string a[50][8];
char *point;
int sayi = 0;
int i = 0;
int j = 0;
point = strtok(kelime_array,",");
while (point!=NULL){
    cout  << " ";
    for(i = 0 ; i<50 ; i++){
        for(j = 0; j<8; j++){
            a[i][j] = point ;
            cout << a[i][j] << " ";
            point = strtok(NULL,",");
        }
    }
}

    cout << a[0][1] ; // I tried but its not working

    readFile.close();
}

int main(int argc, char** argv) {
    
    ReadFileFunc();
    return 0;
}

Don't use `strtok`, as it modifies the string. Consider using `std::getline(readFile, ',')` — Thomas Matthews, Dec 09 '20 at 21:49
Why do you need a 2d matrix? I recommend creating a struct (or class) that models one record (line of input), then use `std::vector` of that class. — Thomas Matthews, Dec 09 '20 at 21:51
