using namespace std;
int main( )
{
locale loc ( "German_Germany" );
bool result1 = isspace ( 'L', loc );
bool result2 = isspace ( '\n', loc );
bool result3 = isspace ( ' ', loc );
if ( result1 )
cout << "The character 'L' in the locale is "
<< "a whitespace character." << endl;
else
cout << "The character 'L' in the locale is "
<< " not a whitespace character." << endl;
if ( result2 )
cout << "The character 'backslash-n' in the locale is "
<< "a whitespace character." << endl;
else
cout << "The character 'backslash-n' in the locale is "
<< " not a whitespace character." << endl;
if ( result3 )
cout << "The character ' ' in the locale is "
<< "a whitespace character." << endl;
