Make sure your code is [code]between code tags[/code] so that it has line numbers and syntax highlighting, as well as proper indentation.

        std::cout << "....5" << std::endl;
        std::cout << "...45" << std::endl;
        std::cout << "..345" << std::endl;

    return 0;
}

How common is it to have the std::cin inside of the if statement rather than before?

[LB]

It's more common with other kinds of input streams. In this case, having the input operation as part of the condition means that the if statement will evaluate to false if you type something that isn't a number. More detail:
