Example:
Test for a decimal digit.
<ctype.h>
int isdigit(int c);
c
Returns a non-zero integer value if the character is a digit; otherwise,
returns zero.
A character is considered to be a digit character if it is in the range of
‘0’- ‘9’.
#include <ctype.h> /* for isdigit */
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
3 is a digit
# is NOT a digit
Test for a graphical character.
<ctype.h>
int isgraph (int c);
c
Returns a non-zero integer value if the character is a graphical charac-
ter; otherwise, returns zero.
A character is considered to be a graphical character if it is any print-
able character except a space.
#include <ctype.h> /* for isgraph */
#include <stdio.h> /* for printf */
int main(void)
{
int ch;
ch = '3';
if (isdigit(ch))
else
ch = '#';
if (isdigit(ch))
else
int ch;
printf("3 is a digit\n");
printf("3 is NOT a digit\n");
printf("# is a digit\n");
printf("# is NOT a digit\n");
