Hi kensy11,

you can use functions like 'isupper', 'isdigit', 'ispunct' and some more to get those infos about a 'char' here you can find some more: http://man.cx/isdigit%283C%29

Hope that helps,

Take a look at isupper() http://www.cplusplus.com/reference/clibrary/cctype/isupper/Notice the list on the left bottom part of this page. It has other functions that you may find useful. For example, ispunctislowerisspaceisprintisdigitisalphaisalnum

so there is no way i could use
#include <stdio.h>
#include <conio.h> for checking that ?

i shuld use
#include <stdio.h>
#include <ctype.h>

???

You can use conio.h if it is working with getch.
You should also include ctype.h in order to use islower, etc.

Note that isupper returns a true (i.e., any value other than 0) if and only if two conditions are met:1) key is an alphabetic letter2) and this alphabetic letter is uppercase
