Output:
& is NOT a white-space character
a tab is a white-space character
Test for an upper case letter.
<ctype.h>
int isupper (int c);
c
Returns a non-zero integer value if the character is an upper case
alphabetic character; otherwise, returns zero.
A character is considered to be an upper case alphabetic character if it
is in the range of ‘A’-‘Z’.
#include <ctype.h> /* for isupper */
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
B is upper case
b is NOT upper case
Test for a hexadecimal digit.
<ctype.h>
int isxdigit (int c);
c
Returns a non-zero integer value if the character is a hexadecimal digit;
otherwise, returns zero.
A character is considered to be a hexadecimal digit character if it is in
the range of ‘0’-‘9’, ‘A’-‘F’, or ‘a’-‘f’. Note: The list does not include the
leading 0x because 0x is the prefix for a hexadecimal number but is not
an actual hexadecimal digit.
int ch;
ch = 'B';
if (isupper(ch))
else
ch = 'b';
if (isupper(ch))
else
printf("B is upper case\n");
printf("B is NOT upper case\n");
printf("b is upper case\n");
printf("b is NOT upper case\n");
