Thread: chess program for movement of queens and pawns...

i am a student working on this and i am looking for some help... if you want a copy of what i have leave me an email address

What are you struggling with? We also have an AI board if the trouble is in that sector

not AI... there is no Ai in this one... its supposed to be simple... i can not seem to get my queens to move as they should

if i can send you the file would u be able to help me?

anyone?

id rather send it... i tried posting code but it didnt work

ill send you the text file

?????

The only reason I can think of that posting didn't code work is the tags
http://cboard.cprogramming.com/showthread.php?t=25765

From what I've seen, people don't really do 1-1 things like aim, so for best chance of help...find some way to express the question here

ok...

Code:

 } //end queens move

thats the problem area... all variables are declared before and stuff like that... disregard the comments.... shows frustration.... any help would be great

anyone???

Sometimes it is useful to take out a piece of paper, and right down an algorithm in pseudocode (or draw a diagram, or something).

If you can't do this, then you won't be able to code a solution and will instead wind up with a mess.

Another suggestion, look up how to properly format your code.
