C iscntrl(). The iscntrl() function checks whether a character is a control character or not. Characters that cannot be printed on the screen are known as control 

Tests for any character that is a lower-case letter or is one of the current locale-defined set of characters for which none of iscntrl(), isdigit(), ispunct(), isspace (), or isupper() is true. In the “C” locale, islower() returns true only for the characters defined as lower-case ASCII characters. Default isprint() The iscntrl () function tests for any control character. An ASCII control character is any character whose value is between 0 and 31.
