Input/Output

• Decimal:
  

  $$o\in\texttt{ostream}, a\in\textsf{Rational}$$ Input:

  $$o\in\texttt{ostream}\quad\Box$$ Output:

  $$i\in\texttt{istream}$$ Input:

  $$i\in\texttt{istream}, a\in\textsf{Rational}\quad\Box$$ Output:

• Internal Representation:
  

  $$o\in\texttt{ostream}, a\in\textsf{Rational}$$ Input:

  $$o\in\texttt{ostream}\quad\Box$$ Output:

  Note: puts internal representation of Rational a on an output stream.

  $$a\in\textsf{Rational}, i\in\texttt{istream}$$ Input:

  $$a\in\textsf{Rational}, i\in\texttt{istream}, b\in\texttt{bool}\quad\Box$$ Output:

  Note: gets Rational a as an internal representation from input stream if b is true.
