Interpreter for enhanced version of IMP (Simple Imperative language).
I have enhansed it with few more operators like subtraction, multiplicatoin etc. IMP has only one type which is Int, but I added Boolean and Strings. I have introduced print statement as well.
Examples of valid programs are in *.imp files
Link to the language description: http://fsl.cs.illinois.edu/images/0/0d/CS522-Spring-2011-PL-book-imp.pdf
Code compiles with ghc --make IMP_Interpreter.hs
and starts with ./IMP_Interpreter test.imp
