    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.*
