This will do it.
if (!(((value >= 'a') && (value < = 'z')) ||
((value >= 'A') && (value < = 'Z'))))

The best way to do this is:
if ( ! isalpha ( value ) )
isalpha is the ISO standard function from ctypes.h that tells you whether the character is alphabetic.
You can write a test like ('a'<=value && value<='z') || ('A'<=value && value<='Z') but that is of limited use and shouldn't make it into commercial software. It's fine in Italy for Italian words, but anywhere like the UK or USA where there is the occassional use of accented or non-Roman letters it fails (e.g. Beyoncé with an é at the end).

yeah dude..:)
* you can get the value as an integer datatype and check it whether the inputted data ranges from ASCII code of alphabets(i.e., from A to Z and from a to z)
check it out..:):)
