## Overview

AEP-2S is a small Windows console application for managing usernames and passwords. Its visible workflow starts in the menu, where the add-user action validates and confirms a password, sorts the in-memory users, and saves them. Other implemented operations include listing, changing, and deleting users. User records are stored in users.txt, with the program applying a reversible character transformation when displaying or persisting passwords. The excerpt is incomplete, so menu dispatches beyond adding a user are not shown.

Main entry points: [`AEP 5.0.cpp`](https://github.com/augxusto/aep-2s/blob/main/AEP%205.0.cpp) (Add user)
