#define ENDFILE "CTRL-Z"

this end the file whenever the user enter CTRL-Z
what i need, i want the user 2 enter CTRL-X to end the program

#define ........ "CTRL-X" ( what could i write here)
so the program end whenever the user press CTRL-X

Are you using the

#ifndef CTRL-X_H
#define CTRL-X_H

#endif

#define ENDFILE "CTRL-Z"

You have them enter this text? Or are you meaning a single keystroke? (If you mean a keystroke, I'd guess you're not doing this right.)

what i need, i want the user 2 enter CTRL-X to end the program

#define ........ "CTRL-X" ( what could i write here)

If you are trying to intercept keystrokes, you may be interested in signals.
