A slightly more interesting question since I've not actually written
that program before. I don't think you can easily handle UTF-8 using
the non-wide versions of isxxxx, but this should do it:
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include <locale.h>
#include <wchar.h>
#include <wctype.h>
int main(void)
{
setlocale(LC_ALL, "");
wint_t wc;
unsigned nl = 0, nd = 0;
while ((wc = getwchar()) != WEOF) {
nl += (bool)iswalpha(wc);
nd += (bool)iswdigit(wc);
}
printf("%u %u\n", nl, nd);
return ferror(stdin) ? EXIT_FAILURE : EXIT_SUCCESS;
}
