Hi,
I'm looking for some C equavilents to these java functions:

char c = someChar;
boolean isWhitespace = Character.isWhitespace(c);
boolean isDigit = Character.isDigit(c);
boolean isLetter = Character.isLetter(c);
boolean isLetterOrDigit = Character.isLetterOrDigit(c);

or something like this (even better):

switch(GetType(c))
{
   case WHITESPACE:
      break;
   case LETTER:
      break;
   //etc...
}

Are there any?

Thanks in advance,
Nille

Look in ctype.h :

isalpha()
isalnum()
isdigit()
islower()
isupper()
isspace()
isxdigit()
iscntrl()
etc.

yep use ctype.h header file for that macros
use this sample program

#include<ctype.h>
main()
{
int ch;

while((ch=getch()) != 'q')
{
if(isalpha(ch))
printf("Alphabet\n");
if(isdigit(ch))
printf("Number\n");
}
}
