int main( )
{
locale loc ( "German_Germany" );
bool result1 = iscntrl ( 'L', loc );
bool result2 = iscntrl ( '\n', loc );
bool result3 = iscntrl ( '\t', loc );
if ( result1 )
cout << "The character 'L' in the locale is "
<< "a control character." << endl;
else
cout << "The character 'L' in the locale is "
<< " not a control character." << endl;
if ( result2 )
cout << "The character-set 'backslash-n' in the locale\n is "
<< "a control character." << endl;
else
cout << "The character-set 'backslash-n' in the locale\n is "
<< " not a control character." << endl;
if ( result3 )
cout << "The character-set 'backslash-t' in the locale\n is "
<< "a control character." << endl;
else
cout << "The character-set 'backslash-n' in the locale \n is "
<< " not a control character." << endl;
}
