isxdigit (Continued)
Example:
#include <ctype.h> /* for isxdigit */
#include <stdio.h> /* for printf */
int main(void)
{
int ch;
ch = 'B';
if (isxdigit(ch))
printf("B is a hexadecimal digit\n");
else
printf("B is NOT a hexadecimal digit\n");
ch = 't';
if (isxdigit(ch))
printf("t is a hexadecimal digit\n");
else
printf("t is NOT a hexadecimal digit\n");
}
Output:
B is a hexadecimal digit
t is NOT a hexadecimal digit
tolower
Description:
Include:
Prototype:
Convert a character to a lower case alphabetical character.
<ctype.h>
int tolower (int c );
Argument:
c
The character to convert to lower case.
Return Value:
Remarks:
Example:
? 2008 Microchip Technology Inc.
Returns the corresponding lower case alphabetical character if the
argument was originally upper case; otherwise, returns the original
character.
Only upper case alphabetical characters may be converted to lower
case.
#include <ctype.h> /* for tolower */
#include <stdio.h> /* for printf */
int main(void)
{
int ch;
ch = 'B';
printf("B changes to lower case %c\n",
tolower(ch));
ch = 'b';
printf("b remains lower case %c\n",
tolower(ch));
ch = '@';
printf("@ has no lower case, ");
printf("so %c is returned\n", tolower(ch));
}
