Strictly C Programming -- 2

When an attacking robot connects to the server of a defending robot via port 0000, the
connection is considered a challenge and the game begins immediately: the defender
automatically plays white (he, therefore, has the advantage) and the attacker automatically
plays black.
Such a challenge can be issued to each server once a day (including yourself). You can play
more games, but they will not be saveable.
The board is numbered with the Manoury notation:
— we visualize the board on the white player side (the whites start at the bottom, the blacks
at the top),
— only the black squares are numbered (those on which we play),
— the black squares are numbered from left to right then from top to bottom starting from 1
to 50.
