Flex & Bison project - operations on strings

Hi.

I need program using Flex and Bison doing operations on strings.

It has to be able to: merge strings, reverse them, taking only first/last word, cutting first/last word, looking for maximal prefix-sufix. Also it needs to have the ability to assign string to variable. The simpler, the better.

It should be connected in a way like in this tutorial: [url removed, login to view]

Operations ofcourse should be done in c functions or c++. Examplary runtime:

Input: a = test text it is

Output: assigned

Input: a

Output: test text it is

Input: b = second test yeah

Output: assigned

Input: merge(a,b)

Output: test text it is second test yeah

Input: reverse(a)

Output: si ti txet tset

Input: takefirst(a)

Output: test

Input: takelast(a)

Output: is

Input: cutfirst

Output: text it is

Input: cutlast(a)

Output: test text it

At the end I will need Flex file, Bison file and Makefile. Comments would be also welcome.
