Hello I'm actually programming a game in c++ and SFML and I would like to know how to wright the text of dialog Box in my code (I'm french so I write original dialog in french and I need to change them easely .

&

I also need to know how to read line per line in a file open with iostream. In fact I have to say to my code "go pick that info at X line"

Thanks you in advance for your answer and sorry for my bad english

Reading a file line by line is as easy as:

  ifstream src(__FILE__);
  if (!src)
  {
    perror(nullptr);
    return errno;
  }
  string line;
  while (getline(src, line))
  {
    // do sth. with line
  }

If you need to access lines by number it might by an option to store them in a vector.

Since I am not a SFML guy I can't help with the dialog box.

Hello ,
Thanks for your answer but I still not understand . Can you not try to use vector in your example ? Thank you in advance :)

Here you go.

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

using std::cout;
using std::cin;
using std::string;
using std::vector;
using std::ifstream;

int main()
{
    vector<string> lines; // create an empty vector of strings
    ifstream src(__FILE__);
    if (!src)
    {
        perror(nullptr);
        return errno;
    }
    string line;
    while (getline(src, line))
    {
        lines.push_back(line);
    }

    // just to see if we read all lines correctly

    for(const string& s : lines)
      cout << s << "\n";
}
