Write A C++ library integer.h that defines a numerical class implementing arbitr

Question

Write A C++ library integer.h that defines a numerical class implementing arbitrary precision integers and operators?

NOTE:

- Your class should support creation from int or string.

- Any valid int literal or variable should be correctly converted into an Integer.

- Valid string literals or variables should be converted. The base of the string literal is always 10, and the value may have a leading - sign to indicate negative values.

NOTE:

Your class should overload the following operators:

- addition, multiplication, subtraction, division, remainder (+*-/%)

- stream insertion and extraction (<< and >>)

- increment, decrement (post- and pre-) (++,--)

- negation (unary -)

- equal, not equal, less than, greater than, less-than-or-equal-to,greater-than- or-equal-to (==,!=,<,>,<=,>=)

- compound operators: +=,-=,*=,/=,%=
