    Question Please Some Advice?

    Hey guys If I want to just read the last line of a txt file and display it how could I do that?

    for example if I want to read the whole file with this info but I need to cout just the last line ?

    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.
    #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.*
