Number Base Convertercs 122 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 should always be preceded by a "$" and binary numbers by a "%". Other numbers are assumed to be decimal. The program should repeatedly prompt for input and display conversions until "q" is entered.

The purpose of this program is to facilitate the conversion of numbers between decimal, hexadecimal, and binary systems. Such conversions are fundamental in computer science, especially for understanding low-level data representations, debugging, and working with different programming environments. By creating an interactive tool, students can familiarize themselves with number systems and improve their understanding of base conversions.

The approach involves designing a top-down algorithm that handles user input, determines the input number's base, performs conversions among the various bases, and displays the results. The program will continuously accept input until a quit command is issued. The core logic includes identifying the input format based on initial character, converting the input string to a decimal value, then converting this decimal value to binary and hexadecimal representations, and finally displaying all three forms.

The methods involve mathematical processes such as parsing strings into numeric values, and implementing conversion functions: one to convert decimal to binary, another to convert hexadecimal to decimal, and vice versa. Key functions include dec2bin, hex2dec, str2num, and num2str (or their equivalents in MATLAB), which facilitate the conversion process. The program structure will include functions for each conversion, a main loop for repeated operation, and conditional statements to determine the input format.

Implementation comprises reading input as a string, analyzing its first character to decide the type (no prefix for decimal, "$" for hexadecimal, "%" for binary), performing the respective conversions, then printing all three number forms in a formatted output. Proper comments will be included within the source code to enhance clarity and maintainability. The MATLAB script will be organized in a modular fashion, with functions dedicated to each conversion task and a main script managing user interaction.

Significant challenges include correctly parsing the input strings, especially handling edge cases such as empty inputs or invalid characters, and ensuring accurate conversions between bases. These issues are addressed by validating input formats and incorporating error handling routines that prompt the user to re-enter valid numbers. Using MATLAB's string handling and conversion functions simplifies many of these tasks, reducing the likelihood of errors.

In conclusion, this project demonstrates essential programming concepts such as control structures, string processing, modular function design, and numerical conversions. It emphasizes practical implementation of base conversions, a skill crucial for understanding computer architecture and data representation. The completed program serves as an educational tool and a foundation for more complex numerical analysis tasks in computer science coursework.
