this my code so far. I am trying to compile and can't figure out the problem.

[daguanqiao]

add some lines in your code
in line 5

#include <time.h> 

Add to main before the while

char games;

Add to the while() before switch()

scanf("%c",&games);

[abeke]

okay I will see if this works and get back to do

I did very thing but it not saying that scanf is not being declared in the scope

[daguanqiao]

scanf is not declare 。add #include 《stdio.h》
or use the cin replace the scanf 。。the cin grammar I forget

[abeke]

I was able to fix all the errors but now my program is glitching.

[daguanqiao]

sorry ，I do not know what you say,can you statement clearly ？
Now your program is 0 error and warning， but something wrong is alread happend,
the lasted day I use the microsoft visiol studio 2010 run your program , it is successful.
I got the result , when I press ‘w'， it is move.
