The Instructions And Starting Templates For The Assignment Are Attache
The instructions and starting templates for the assignment are attached to this module. Please download them and follow the instructions. There are actually 3 source files/starting templates for this assignment: assg-03.cpp, LargeInteger.hpp, and LargeInteger.cpp. You need to download and use all 3. assg-03.cpp contains the main function and has tests of your code. You should not need to add anything to this file; simply uncomment the tests as you work on your assignment.
The files LargeInteger.hpp and LargeInteger.cpp are the header file and implementation file. You will need to add the function prototypes to the .hpp header file class definitions for the member functions and constructor you create. And likewise, you will need to write and implement your constructor and member functions in the LargeInteger.cpp file.
Paper For Above instruction
This assignment involves creating a class to handle large integers, which are beyond the capacity of standard data types in C++. The task requires understanding of object-oriented programming principles, particularly class design, encapsulation, and member function implementation. By designing a class called LargeInteger, the goal is to facilitate operations on arbitrarily large integers that can be used in various computational contexts, such as cryptography, scientific calculations, and number theory research.
The provided source files—assg-03.cpp, LargeInteger.hpp, and LargeInteger.cpp—form the backbone of this assignment. The main program in assg-03.cpp contains pre-written test cases that verify different features and functionalities of your class implementation. Your primary responsibility is to complete the class definition by adding function prototypes in the header file (LargeInteger.hpp) and then implementing those functions in the source file (LargeInteger.cpp). This separation of declaration and implementation aligns with standard C++ programming practices and promotes code clarity and modularity.
Start by analyzing the provided header file, which likely contains a skeleton of the LargeInteger class. Here, you need to identify which member functions are necessary for your class, such as constructors, destructors, addition, subtraction, and possibly comparison operators. Write the prototypes for these functions in the header file within the class definition. These prototypes specify the function return types, names, and parameters, serving as a contract for what your class will contain. Next, implement the functions in LargeInteger.cpp. The constructor might involve initializing the large
integer from a string or an array representing digits, while other member functions will perform arithmetic operations taking advantage of dynamic memory management and digit-by-digit calculations. Carefully handle memory allocation, deallocation, and edge cases such as leading zeros or sign considerations if applicable.
While working on this assignment, ensure your code is well-documented and includes comments explaining the logic behind complex operations. Test your code thoroughly using the provided main function tests in assg-03.cpp, uncommenting test cases as you develop each feature. This iterative testing approach helps identify bugs early and ensures your implementation behaves as expected for various input scenarios.
In conclusion, this assignment provides hands-on experience in designing a robust C++ class for handling large integers, emphasizing practices such as header/source separation, operator overloading, dynamic memory management, and comprehensive testing. Successfully completing this task will enhance your understanding of advanced object-oriented design and prepare you for more complex C++ programming challenges.
