CSCI 3080 - Discrete Structures

Bonus Lab - Binary, Decimal, Hexadecimal Converter

1. Objective

The goal of this lab is to create a C++ program that converts a number between three numbering systems: binary, decimal, and hexadecimal. Students will gain hands-on experience in base conversions and string manipulation.

2. Requirements

★ (1) Ask the user to choose the input number system (Binary, Decimal, or Hexadecimal).
★ (2) Prompt the user to enter a number in that base.
★ (3) Convert and display the number in all three formats.
★ (4) Use input validation for each base.
★ (5) Include a do-while loop to allow repeat usage.
