/* EXPECTED OUTPUT:
This program has you, the user, choose a number
between 1 and 10, then I, the computer, will try
my best to guess it.

Is it 8? (y/n) n
Is it 7? (y/n) n
Is it 5? (y/n) n
Is it 1? (y/n) n
Is it 8? (y/n) n
Is it 1? (y/n) n
Is it 9? (y/n) y

I got your number of 9 correct in 7 guesses.
