Tokenization of strings

[jpcode]

I am using the following code which can tokenize the strings based on DELIMITER. But I want this data to be saved in a vector such that I can access the data anywhere in my program. Is there any chance without using vectors I could achieve this? Are vectors really useful?

  #include <iostream>
#include <sstream>
using std::cout;
using std::endl;

#include <fstream>
using std::ifstream;

#include <cstring>
#include <vector>

const int MAX_CHARS_PER_LINE = 512;
const int MAX_TOKENS_PER_LINE = 50;
const char* const DELIMITER = " ";

int main()
{
  ifstream fin;
  fin.open("data.txt");
  if (!fin.good()) 
    return 1;
  int j=1;

  while (!fin.eof())
  {
    char buf[MAX_CHARS_PER_LINE];
    fin.getline(buf, MAX_CHARS_PER_LINE);
    int n = 0; 
    std::vector<std::string> token_1[MAX_TOKENS_PER_LINE] = {};
    const char* token[MAX_TOKENS_PER_LINE] = {}; // initialize to 0
    
    token[0] = strtok(buf, DELIMITER);
    if (token[0]) 
    {
      for (n = 1; n < MAX_TOKENS_PER_LINE; n++)
      {
        token[n] = strtok(0, DELIMITER); 
        
        if (!token[n]) break; 
        
      }
      
    }

    for (int i = 0; i<n; i++)
        cout << "Token[" << j++ << "] = " << token[i] << endl; // token[i], this I need to access anywhere in my program.
  }
  cout<<--j<<endl;
}

I want token[i] to be accessed for suppose if I give token[10], I could be able to get the value of that particular token.

No. There is no way you can save stuff in a vector without using a vector.

Well, thanks a lot @cire, how can I use vector to save token[i]? I cannot copy/ assign , it gets lots of errors!

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

void anywhere_in_this_program( std::vector<std::string>& tokens)
{
    for (auto&t : tokens)
        std::cout << t << '\n';    
}


int main()
{
    std::vector<std::string> tokens;

    std::string token;
    while (std::cin >> token)
        tokens.push_back(token);

    anywhere_in_this_program(tokens) ;
}
