can someone please help write a c++ programe for a cows and bulls game??
the game is something like this:


***A bull is a symbol in the guess that matches a symbol of the code both by position and value.
A cow is a symbol in the guess that matches one of the code by value, but not by a position.
example:
the code is : ROYY
yhe guess is: RYBR
then the score would be one bull ( R ) and one cow( Y ).

the program must read some guesses and thier scores.
and output all the codes consistent with the sequence of guesses and responses:
if we enter:
RRRR 2 0
RRBB 2 2

the program must output:
RBRB
RBBR
BRRB
BRBR****

i got the above rules frm some other side. but i dont want the game to be run with letters but numbers, using simple loops and the randomize function.

Thanx.
