BigInteger

This is a C++ implementation of BigInteger

Compiling and Running:

to compile:
$ make
to run:
$ ./main

Constructors:

default - BigInteger a; // a = 0 by default

int - BigInteger a(123), b = -123;

string - BigInteger a("999999999999999999999"); 

Exception Throwing - Runtime Errors:

BigInteger a("foobar"); // throws exception : Invalid value: foobar

BigInteger b("123123s"); // Invalid value: 123123s

Increment and Decrement:

BigInteger a = 123;
a--;
--a;
a++;
++a;

Comparison Operators:

>
<
==
!=
<=
>=

Unary +/-:

BigInteger a = 123;
a = -a; // a = -123
