/*
functions:
main >> output instructions
input P1 name, p2 name
loop{-clearscreen-
output board, compute scores
P1 or P2 turn, output scores
input placement of next piece
check coordinates and flip away}
loop ends when a)P1_score+P2_score=100
b)checker declares there are no moves left
c)Q is entered instead of proper coordinates
ask if player wants another game
checker >> determine whether coordinate input
is valid - within board, adjacent to
appropriate pieces
if input is Q: ask whether player wishes to quit
flipper >> checks horizontally, vertically and diagonally
for pieces that ought to be flipped and flips them
->might be split in three: fliph, flipv and flipd
arrays:
board[11][11] -> play area is 10X10.
row[0] and col[0]for displaying coordinates.
Pl_name[2][8] -> luxury. Player names, 7 char max.
coords[3] -> coordinates for next piece
switches:
quit -> if yes: quit, no: continue, default: ask again;
best be in a loop (for default)
play_again -> if yes: another game, no: exit program
default: ask again (also looped)
