CS 2123 Data Structures Recitation Exercise 07 (Library - Abstract Data Type) Exercise: Reimplementation of RPN calculator and Proper matching ifnde stack h define stadh include cerli typedef void stackElementT typedef struxt tackCDT stcADT Suppose you cannot change stack.h and instead of char or double, it currently exporta typedef void *stackElementaunmeas r an Given this version of stack.h implement RPN calc and proper matching What will be main difference tack, stackElemeMT Popl stackADT stack ackflenereT GetStadflementistadADT stack ntur dex); Dynamically allocate memory for each value that you push, free when you pop and/or reuse 24 In this exercise, you are simply asked to re-implement RPN calculator by using stack.h that exports typedef void *stackElementT; (just doind rpn calc is enough to submit, you can do the proper matching on your own time) First, go to class web site and download the existing stack lib, rpncalc.c and also get books lib For this, follow programs from the textbook" link under online materials in the class webpage http://www.cs.utsa.edu/-korkmaz/teaching/cs get booklib.zip and 08-Abstract-Data-Types.zip save both under a common directory, say X Then follow these instructions: X>unzip booklib.zip X> cd booklib -/X/booklb> make
