This exercise has several steps.

First of all, let the user guess several times (with responses each time), until she finds the hidden number.

Allow various special keys too:

• n - skip the rest of this game (give up) and start a new game with new hidden number.
• s - show the hidden value (cheat).
• m - toggle: turn on/off move mode: When the move mode is on, after every guess the number can change by 2 in either direction.
• d - toggle: turn on / off debug mode. In debug mode show the hidden number every time before you are asked to supply the guess.
• x - exit

Now I can tell you that this is actually a 1 dimensional space fight. The number is your distance from the enemy space ship.

For training purposes limit the outer space to be between 0-200 so even when the move mode is on the space-ship won't fly off this area.

Finaly, keep track of the minimum and maximum score (number of guesses till hit) in a file.
