Synopsis:
    #include <ctype.h>
    int isalpha( int c );

Description:
    The isalpha function tests if the argument c is an alphabetic character
    ('a' to 'z' and 'A' to 'Z').  An alphabetic character is any character
    for which  isupper or  islower is true.

Returns:
    The isalpha returns zero if the argument is not an alphabetic character
    otherwise, a non-zero value is returned.
