logical error entering while

[jumperkid400]

I am attempting to enter a while loop but for some reason my logic is off. It enters the loop exactly when i dont want it to. i want the range to be either 1,2 or 3.

  
cout << "What would you like the difficulty to be? " ;
cin >> difficulty;
while ((difficulty > 0 ))
{
      cout << "That is not a valid difficulty. Please enter a number 1-3.\n";
      cin >> difficulty;
}

If you wanted the number to be 1,2 or 3 I would expect something like this instead.

while ((difficulty <=0 || difficulty >= 4))
{
      cout << "That is not a valid difficulty. Please enter a number 1-3.\n";
      cin >> difficulty;
}

see that confuses the crap out of me only because it seems backwards. I read that like this tell me if im wrong. difficulty is less than or equal to 0 OR difficulty is greater than or equal to 4... so the teh true value would be passed if difficulty was higher than 4 or less than 0

That while loop will run while difficulty is less than or equal to 0 and greater or equal to 4 as you said. The point of that is to keep the user entering in numbers inside the loop until it's between 0 and 4.

Once it's between 1-3 it will skip that loop and continue on to whatever is next.
