SET Calculator README

Introduction

This program is a SET calculator designed to perform various operations on sets. Sets, named SETA to SETF, can hold numbers between 0 and 127. Operations include reading numbers into sets, printing sets, performing union, intersection, subtraction, and symmetric difference operations between sets.

Usage

1. Compilation: Compile the program using the provided Makefile.

   make

   This will generate an executable named a.out.

2. Execution: Run the program by executing the generated executable.

   ./a.out

   This will start the SET calculator.

3. Commands:

   • read_set:
     Read numbers into a particular set. Numbers must be positive integers, separated by commas, and terminated with -1. Example: read_set SETA, 3, 1, 22, -1.
   • print_set:
     Print all numbers inserted into a specified set. Example: print_set SETB.
   • union_set:
     Perform the union operation between three sets. Example: union_set SETA, SETB, SETC.
   • sub_set:
     Perform the subtraction operation between three sets. Example: sub_set SETA, SETB, SETC.
   • intersect_set:
     Perform the intersection operation between three sets. Example: intersect_set SETA, SETB, SETC.
   • symdiff_set:
     Perform the symmetric difference operation between three sets. Example: symdiff_set SETA, SETB, SETC.
   • stop:
     Terminate the calculator.

4. Notes:
   

   • The calculator allows whitespace between commands and parameters but does not allow additional text or commas.
   • Numbers must be integers between 0 and 127.
   • Each command must be followed by the appropriate set names separated by commas.

5. Cleanup: To clean up object files and the executable, run:

   make clean
