Why is it that using some of the macros from ctype.h fails to compile?
In particular, the three mentioned in the subject: line.
Try this:
#include <stdio.h>
#include <ctype.h>
int main(int argc, char *argv[])
{
int i;
for (i = 0; i < 256; i++) {
printf("%3d: ",i);
if (isalpha(i)) printf(" alpha");
if (isalnum(i)) printf(" alnum");
if (isascii(i)) printf(" ascii");
if (isblank(i)) printf(" blank");
if (iscntrl(i)) printf(" cntrl");
if (isdigit(i)) printf(" digit");
if (isgraph(i)) printf(" graph");
if (islower(i)) printf(" lower");
if (isprint(i)) printf(" print");
if (ispunct(i)) punctf(" punct");
if (isspace(i)) printf(" space");
if (isupper(i)) printf(" upper");
if (isxdigit(i)) printf(" xdigit");
printf("\n");
}
return 0;
}
