Checking capital and small characters

Is there any functions to check the character (example 'A') is in caps or small?
if not, what other methods are there?

There are all the is_____ functions in <ctype.h>, such as isalpha, isupper, ispunct, islower, etc. (I'll leave it to you to figure out which ones you want.)

Code:

---

if ('a' > 'b') {
        if ((ch <= 'A') && (ch >= 'Z')) return TRUE;
} else {
        if ((ch >= 'A') && (ch <= 'Z')) return TRUE;
}

return FALSE;

Think that is one way (also) -- that is if I've got all the PacMans in the right direction.

Only if you're using an ASCII machine.
Try that on a Mainframe and it won't work.
Just use the standard C functions if you want to write portable code.

Banks, Insurance companies, Governments...
Those were the main customers at my previous job which made software for mainframes.
