I need help in C Programming?

Question

I am writing an if condition 

it is if(value is not an alphabetic character){
do something

regards
}
I dont know any efficient way of doing it. I can do that but it will be so long

if(value!='a'||value!='b'...............value!='z')
{body}

Does anyone know how to write a condition to exclude all alphabetic characters

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. BeyoncÃ© with an Ã© 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..:):)
