The answer to the first question is easy

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
#include <iostream>
#include <iomanip>
using namespace std;
 
int main()
{
    cout << right << setw(20) << "Hello\n";
}
#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
    cout << right << setw(20) << "Hello\n";
}

For the second question, there is no portable way to do that. Some compilers pre-define macros that indicate the compiler and compiler's version, while other compilers don't. So the only sure-file way to do it is to declare the macros yourself for each compiler you want to support.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
