Large Number Class

Short Description:

Create a large number integer class.

This assignment is worth 60 points.

Goals

When you finish this homework, you should:

Have developed your skills designing and implementing a class.
Have developed your skills implementing overloaded operators and functions.
Have developed your skills implementing friend functions.
Have demonstrate you skills documenting an interface.
Have developed your skills buiding muliple file implementations.

Formal Description

The program to calculate pi included with the demonstration rational number class fails with the addition of the value 4/25. This is due to numeric overflow attempting to add this value into the sum.

This problem can be overcome by implementing a large integer class. This class would store the digits of a number in some type of data structure, perhaps an array. The class would also provide the operations necessary for normal programming, especially those needed by the rationalT class.

The class should be constructed in a manner such that it can be used in multiple programs (header and implementation files). As such, the header file should be documented following the examples on page 614 of your book. You should document your implementation file, as well as your drivers according to my standards.

You should implement two programs, the first should be a driver which tests all aspects of your class. The second should allow a user to compute factorial for large numbers (60! = 8320987112741390144276341183223364380754172606361245952449277696409600000000000000).
