Project case study
C++ command-line utilities
A menu-driven application combining arithmetic, statistics, a Caesar-cipher exercise, and random password generation.
The problem
Several small utilities need a common interaction pattern: choose a function, provide input, receive a result, and return to the menu. This project brings those exercises together in one command-line program.
The application includes arithmetic operations, mean/median/mode calculations, a Caesar-cipher exercise, password generation, and an exit flow.
Design & implementation
Separate responsibilities
The main program handles menu selection and delegates utility behavior to separate implementation and header modules. This keeps navigation distinct from the calculation and transformation logic.
Work with structured input
The statistics implementation works with collections of values and includes input-handling logic. The source is an example of using standard-library containers and algorithms in a small interactive application.
Keep exercise scope clear
The Caesar cipher and password generator are programming exercises. They are not presented as security tools or cryptographically reviewed implementations.
Evidence & verification
The public repository exposes the main program and utility modules, including the statistics implementation. It does not include an automated test suite or recorded test results.
Input validation can be inspected in source. A stronger next step would be a repeatable test set covering invalid menu input, empty or malformed statistics input, arithmetic edge cases, and transitions back to the menu.
What would strengthen the project
Separating calculation functions from console input would make them easier to test. Build instructions and sample sessions would make the program easier for another person to run and assess.
