fair knowledge : you're not surprised when the compiler complains about some error.

good-knowledge : you're able to write a program that will compile at the first attemp (say, the second and we're covered)

guru-knowledge : by just looking at someone else's code, you can guess what's wrong with it.

then i guess i have good knowledge, if you dont count stupid errors liek forgotten semi-colons

Well do you under stand this?:

void msg( char* msg )
{
char curchar;
curchar = *msg;
while ( curchar != '\0' )
{
putch( curchar );
msg++;
curchar = *msg;
}
}//( didn't test if that has bugs...)

i hope that is not the test to see if you are a guru...........because that was way to easy to figure out

No...that is not hard...I know..but if you don't even know what that does than you need to know more C/C++.
