\section*{Homework 8}

\begin{enumerate}
\item Write a program in the WHILE-language that calculates the factorial function.

\item What optimisations could a compiler perform when compiling a WHILE-program?

\item What is the main difference between the Java assembler (as processed by Jasmin) and
Java Byte Code?

\item Parser combinators can directly be given a string as input, without the need of a lexer. What are
the advantages to first lex a string and then feed a sequence of tokens as input to the parser? 
\end{enumerate}
