that is...i don't know about that....maybe you can help me to check thiss...i'm so dizzy about that...thanks if you want to help me....From Agus...

Unless you tell us what is your code supposed to do and what problem are you facing, you will not get any help.

oh i see...this is Tata Surya.... i want build Tata Surya...but it was error... that error is #include<GL/lut.h> no open directory... i dont know about it..maybe you can tell me...about #include this..why is not open

use:

#include <GL/glut.h>

instead of:

#include<GL/lut.h>

I think that you know how to include a file in your source code so that you wrote something like this.

Good luck.

switch ( Key ) {
case 'R':
case 'r':
Key_r();
break;
case 's':
case 'S':
Key_s();
break;
case 27:
exit(1);
}

Consider using tolower() or toupper() from <ctype.h>.

consider moving lines 10 thru 12 to the top of the program, above line 1. Traditionally include files go at the top of the programs and everything else follows. Sometime its a lot more than just tradition but a requirement :).

Without knowing more about what your program is supposed to do, and what it does not do that it should, can not answer any more.
