int main( )   
{
   locale loc ( "German_Germany" );
   bool result1 = isupper ( 'L', loc );
   bool result2 = isupper ( 'n', loc );
   bool result3 = isupper ( '3', loc );

   if ( result1 )
      cout << "The character 'L' in the locale is "
           << "a uppercase character." << endl;
   else
      cout << "The character 'L' in the locale is "
           << " not a uppercase character." << endl;

   if ( result2 )
      cout << "The character 'n' in the locale is "
           << "a uppercase character." << endl;
   else
      cout << "The character 'n' in the locale is "
           << " not a uppercase character." << endl;

   if ( result3 )
      cout << "The character '3' in the locale is "
           << "a uppercase character." << endl;
   else
      cout << "The character '3' in the locale is "
