    by the way the file is going to change once in a while so how could I create a loop that will run until the last line and display it ?

    Maybe something along this line.
    Code:
    #include <iostream>
    #include <fstream>
    #include <string>
     
    int main()
    {
       std::ifstream file("file.txt");
       std::string line, last;
       while ( getline(file, line) )
       {
          if ( line != "" )
          {
             last = line;
          }
       }
       std::cout << "This is the last line of the file:\n"
                 << last << '\n';
       return 0;
    }
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
