Std ofstream append to file

If you want to append, use output. The reference link above shows the possible options. Seperate options by the bit-operator or symbol. Edit: ios::out explicitly says open for output, rather than input. It is usually a good idea to include this even if you are using a specific ofstream or ifstream object, since it helps with readability and the compiler can catch you doing something stupid in case you forget somewhere in your code.

Questions: I wrote a simple program to play around with in-place creation of objects inside standard library containers. Questions: How can I make this simple class movable? Add menu. It's well described in the std::ofstream constructor documentation.
