Small game, in which it must discover 4 numbers hidden in maximum 10 tried to you. For hour it is developed without graphical interface, but only via shell/terminal, but only for hour! The previewed modalities of game are: - alone; - vs CPU, with IA; Previewed the creation of the GUI by means of bookcases GTK. Last scope of the plan is that one to allow the customers to implement the own one ia for the player “Cpu”. The multiplayer….perhaps a day! All the plan is totally free, covered from licence GPL. The used language is the C/C++. This is a plan to pure didactic scope.
