Description
Tests for printing character.
isprint is a macro that classifies ASCII-coded integer values by table lookup. The macro is affected by the current locale’s LC_CTYPE category. For the default C locale, c is a printing character including the blank space (‘ ‘).
You can make this macro available as a function by undefining (#undef) it.
Return Value
isprint returns nonzero if c is a printing character.
Example
#include <stdio.h>
#include <ctype.h>
int main(void)
{
char c = 'C';
if (isprint(c))
printf("%c is a printable character\n",c);
else
printf("%c is not a printable character\n",c);
return 0;
}
