Argument:
Return Value:
Remarks:
Example:
#include <ctype.h> /* for isalpha */
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
B is alphabetic
# is NOT alphabetic
Test for a control character.
<ctype.h>
int iscntrl(int c);
c
Returns a non-zero integer value if the character is a control character;
otherwise, returns zero.
A character is considered to be a control character if its ASCII value is
in the range 0x00 to 0x1F inclusive, or 0x7F.
#include <ctype.h> /* for iscntrl */
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
B is NOT a control character
A tab is a control character
int ch;
ch = 'B';
if (isalpha(ch))
else
ch = '#';
if (isalpha(ch))
else
char ch;
ch = 'B';
if (iscntrl(ch))
else

if (iscntrl(ch))
else

printf("B is NOT alphabetic\n");
printf("# is alphabetic\n");

printf("B is a control character\n");
printf("B is NOT a control character\n");
printf("A tab is a control character\n");
printf("A tab is NOT a control character\n");
