2.22.9.iscntrl

#include <iostream>

using std::cout;

using std::endl;



#include <cctype>

using std::iscntrl;

using std::isgraph;

using std::isprint;

using std::ispunct;

using std::isspace;



int main()

{

   cout << "\nAccording to iscntrl:\nNewline " 

      << ( iscntrl( '\n' ) ? "is a" : "is not a" )

      << " control character\n"

      << ( iscntrl( '$' ) ? "$ is a" : "$ is not a" )

      << " control character\n";

   return 0;

}

According to iscntrl:
Newline is a control character
$ is not a control character
