Hi all I'm not too good at working with files, they confuse the hell out of me. However i have this class, let call it test.cpp

Qt Code: 
  1. #include <iostream>
  2. #include <string>
  3. #include <fstream>
  4. #include <QtGui>
  5.  
  6. using namespace std;
  7.  
  8.  
  9. class test {
  10.  
  11. private:
  12.  
  13.  
  14. public:
  15.     ifstream myfile;
  16.     bool open_file();
  17.     void close_file();
  18.     void next_question();
  19. };
  20.  
  21. bool open_file(){
  22.  
  23.     myfile.open("C:\\test.txt");
  24.     if(myfile.is_open()){
  25.         qDebug() << "Open";
  26.         return true;
  27.     }
  28.     else
  29.     {
  30.         qDebug() << "Error - file not opened";
  31.         return false;
  32.     }
  33. }
  34.  
  35. void close_file(){
  36.  
  37.     myfile.close;
  38.  
  39. }
  40.  
  41.  
  42. void next_line(){
  43.  
  44.     if(open_file()){
  45.  
  46.            // Code here to do stuff with myfile
  47.  
  48.     }
  49.     else
  50.     {
  51.         qDebug() << "File not opened";
  52.     }
  53.  
  54.  
  55. }
To copy to clipboard, switch view to plain text mode 


The error i keep getting is:

" 'myfile' was not declared in this scope. "

How do i work with myfile across all of my functions within a class?


Thanks for your time and trouble
