2.22.12.isgraph

#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 isgraph:\n"

      << ( isgraph( 'Q' ) ? "Q is a" : "Q is not a" )

      << " printing character other than a space\nSpace " 

      << ( isgraph(' ') ? "is a" : "is not a" )

      << " printing character other than a space" << endl;

   return 0;

}

According to isgraph:
Q is a printing character other than a space
Space is not a printing character other than a space
