Project 2: Number Base Converter - 25 Points

Project 2 Number Base Converter 25 Points

Write a program that allows numbers to be entered in decimal (base 10), hexadecimal (base 16), or binary (base 2), and then prints out the number again in all three bases. To distinguish between different bases, hexadecimal numbers are preceded by a "$" and binary numbers by a "%". Other numbers are assumed to be decimal. When the program runs, it should repeatedly prompt for a number, convert it to all three bases, display the results, and continue until "q" is entered.

The objective of this project is to develop a robust program that can convert numbers among decimal, hexadecimal, and binary systems, providing a comprehensive understanding of number base conversions. This task emphasizes practical skills in programming, including the use of functions, string handling, loops, and conditional logic, all of which are essential for building flexible and efficient software applications.

To achieve this, the program must accept input in multiple formats: decimal numbers without a prefix, hexadecimal numbers with a "$" prefix, and binary numbers with a "%" prefix. The core logic involves identifying the input type based on the first character (or absence thereof), converting the input string into a numeric value, and then displaying its equivalent in all three bases. The process needs to be repeated until the user indicates termination by entering "q".

Designing the program begins with defining a clear algorithm — first, prompting the user for input; second, checking if the input is "q" to exit; third, determining the input type based on the first character; fourth, converting the input to an integer using suitable functions; fifth, converting this integer into binary and hexadecimal formats; and finally, displaying all three representations. The loop structure, most suitably a while loop, will enable continuous operation until termination.

Key functions required include custom conversions such as dec2bin for converting decimal to binary and hex2dec for hexadecimal to decimal. MATLAB’s in-built functions like str2num and num2str can facilitate general string-to-number conversions. For conversions from decimal to binary, iterative or recursive logic will be used to generate the binary string. Similarly, converting from hexadecimal to decimal can leverage MATLAB's hex2dec, while vice versa can utilize dec2hex.

Implementation entails writing a main script in MATLAB with appropriate input prompts and conditional logic to distinguish input types, invoking conversion functions accordingly, and formatting the output for clarity. The program should include comprehensive comments explaining each part of the code to improve readability and maintainability.

In constructing the report, it’s important to document the purpose clearly, outline the approach taken during development, describe the methods—specifically the mathematical and conversion techniques used—and include the source code with inline comments. Reflection on any challenges faced, such as edge case handling or string parsing issues, and how they were addressed, should also be incorporated. Including sample outputs for the test cases “16,” “%1111,” and “$6D” will demonstrate the program’s correctness and robustness.
