Wrapping Up

Regular C++ data types struggle with handling large numbers. Utilizing object-oriented programming, we created a custom data type (via a class) that seamlessly mimics primitive data types in C++. We implemented a library to facilitate easy arithmetic operations on these large numbers through operator overloading.

We explored copy constructors, assignment operators, and destructors to deepen our understanding of managing memory for sizable integers. In practical exercises, we performed addition, subtraction, and comparison on these large numbers. Basic arithmetic and comparison operations set the stage for multiplication and division. We saw how a naive implementation could be very impractical and could cost us a lot, so we challenged ourselves to come up with an efficient technique that could solve multiplication and division in a practical time frame.

Finally, we incorporated all operations into a menu-based implementation, merging previous concepts and demonstrating the ease of integration into any application as an external header file.
