Apprentices and Pandawans, we have a load of crap here. I do not wanna 
repeat nor quote it here.

Write a simple C program to count the letters and numbers in this load 
of crap.

Please, I beg you all, do NOT copy and paste existing solutions. Use 
your brain! :)

I can't. System reports a Clown Overflow everytime it encounters "trump".

Ok, ok...

#include <stdio.h>

int main()
{	
    char	chewb;	/* current character being processed */
    int	r2d2,	/* number of numbers */
    	c3po;	/* number of letters */

    while ((chewb = getchar()) != EOF)
       if ((chewb >= 'a' && chewb <= 'z') || (chewb >= 'A' && chewb <= 'Z'))
          ++c3po;
       else if (chewb >= '0' && chewb <= '9')
          ++r2d2;

    printf("Number of letters: %i\nNumber of numbers: %i\n", c3po, r2d2);
    return 0;
}

Be careful to only run this once. Chewbacca doesn't like doing all the hard
work, and letting the droids get away with the results.

Thanks! Need I compile this specific C program using a specific C 
compiler?  :)

Please do not cross-post this C rubbish to alt.fan.starwars
C is a disgusting programming language anyway - use a real programming
language like Pascal or BASIC  :-p

Wanna teach some Pandawans to program in C.

Would Donald Trump master C programming as an Apprentice? :)

Well... It's not THAT complicated. I think this is all TCPL chapter 1 stuff.
Would be surprised if there's anything calling itself a C compiler that
can't handle this. :D

Modify this program to count any char[1]! :)

Why not modify it to be correct first?  I think Robert is pulling your
leg which is why, I suspect, no one has said anything so far.

Let's focus on the homework first. DO you wanna show us how to modify it 
to count char[1]? :)

Note that r2d2 and c3po are not initialized.

Incrementing an uninitialized variable.

True, but C is a case sensitive language, and r2d2 and c3po were not 
initialized.

I prefer isalpha() - it's simpler, and equivalent in the "C" locale. In 
other locales, if there's a alphabetic character for which isalpha() is 
true, but islower() and isupper() are both false, I think such 
characters should be included in the letter count. 7.4.1.2p2 permits 
this, so long as icntrl(), isdigit(), ispunct() and isspace() are also 
false for such characters.
