Daily programming challenge #5 The lost challenge

Difficulty: Hard!

In challenge #1, we created a programm, which parsed a string and gave out the string, that was to write.

NOW: Let's imagine, we want to create Variables in our Interpreter.

EXAMPLE:

INPUT (=File):

new_int_var (Hello = 123)

write (Hello + " HI")

OUTPUT (Terminal or output-field):

123 HI

HOW TO DO THAT? Well, first we need to parse the command and the arguement to it.

BUT: thats not the problem. We need to add an array, which saves the 1-NAME and the 2-VALUE. Once you add string-variables, you need to add the 3-TYPE.

EXTENSIONS:

EX1: add string-variable-types

EX2: add a function for input

EX3: BE HAPPY, THAT YOu JUST WROTE A BASIC INTERPRETER (this isn't something, everybody can do.)

BTW: If you are german and want to see my interpreter (#competition), check out

As this is a really difficult question, feel free to ask me at any times. BUT don't post the answer to others ;-)
