Big-Integer-Representtion

Description :

To implement Big Integers and perform calculation (big integer are those which do not have 
any maximum or minimum value they can be build until computer runs out of memory).

Operations

1. Addition
2. Subtraction
3. Multiplication

All Files with description:

1. BIR.cpp     : It contains the BIR class which is used to create and perform operation on Big Integers.
2. VALID.cpp   : It contains VALID class which is used to validate the Big-Integer(strings) using regex.
3. ERRORH.cpp  : It cotains ERRORH class to handle & display Errors.
4. CONTROL.cpp : It cotains control parameters (symobilc constant) to manage validation, and flow of program.

Prerequisites :

  •	A 32-bit or 64-bit operating system(like Ubuntu, Windows or mac.......)
  •	C++ compiler like g++ and using c++11 version of g++ compiler for regex.

Running :

  On Ubuntu :
        •	$g++ -std=c++11 <Program_name.cpp> -o <exe_filename>
        •	$./<exe_filename>

  On Windows :
        •	open any IDE (like code-block, devc++, ...) and click on Compile and Run option.

  On Dos :
        •	First set the path of IDE.
        •	Open Command Prompt and type $g++ -std=c++11 <Program_name.cpp> -o <exe_filename> (To compile program)
        •	FOR RUNNING PROGRAM TYPE ANY OF THE FOLLOWING SEQUENCE:-
                    •	<exe_filename> <input_file> <output_file>
                    •	<exe_filename> <input_file>
                    •	<exe_filename>
