merging programs

[happy85]

Ok so we have made a test exam program I got that to work. we needed to make a menu driven program got that to work. Now I have to pull it together where if they hit the number one it pulls up the test bank if they hit two its basically the answers. so number 2 or case 2 I had working but when I was trying to integrate my test into case one it doesn't work. I'm just trying to figure out how to make this work I'm sure its all jacked up but if someone can help.

makeLowerCase ( userInput ) == "Start" 

I don't know what it should be doing, but by the looks of it, you are comparing something lowercase to not lowercase.

[Thomas1965]

I think you should use functions to structure your program. In a structured program you can find problems much easier.

int main ()
{
  int counter, choice;
  do
  {
    cout << "1) Load an exam" << endl;
    cout << "2) Display an exam" << endl;
    cout << "3) Quit program" << endl;
    cin >> choice;
    switch (choice)
    {
    case 1:
      LoadExam ();
      break;
    case 2:
      DisplayExam ();
      break;
    case 3:
      cout << "Thanks. See you again, later.." << endl << endl;
      return 0;
    default:
      cout << "Options are only choices 1 to 3..  Thank you." << endl;
    }
  } while (choice >= 1 || choice <= 3);
  
  return 0;
}
