help please.

Line 28.. What is kbhit? you haven't defined it anywhere...
Also, line 95.. infinite loop.. Why not give an exit option...
Sorry, but can't understand about the body problem... You got any compiler errors?
Lynx876 (742)
You need to add more information to your post. What is it you're having problems with, making the body?

Caprico, kbhit() is a function within conio.h. http://www.cprogramming.com/fod/kbhit.html

And nethoinkz, Caprico is correct, you need to add a break; to exit the loop. Seeing as it's within the settings( entering speed etc), You could add an option to type something to exit, which would change a bool:

1
2
3
4
5
6
7
8
9
10
11
 
    bool exit = false;

    do
    {

    //code

    if( /*exit typed in*/ )
        exit = true;

    }while( ! exit);

there is no body when moving up and left. :(
Lynx876 (742)
This wont even compile for me.

You have:
const int length=5, rHead=6, cHead=8;

And then:
1
2
 
if (direction=='w')
                    rHead--;


You're trying to change a constant value!


kbhit() is deprecated, you should use: _kbhit()

As for not having a body while going up or left, I don't quite understand your code :/ lol
