## Overview

ATM Simulator is a Windows desktop application for customer banking and ATM administration, backed by MySQL. The intended customer flow is login, account selection, then banking operations with updated balances and transaction history; administrators manage customers, accounts, ATM cash, and account services. Sampled code confirms database initialization, customer authentication/account persistence, and transfer and withdrawal database access. Other documented capabilities are represented by their source paths, but their internal wiring is not asserted because those implementations were not sampled.

Main entry points: [`ATM1/ATM1/Program.cs`](https://github.com/axb2002/guichetatm/blob/main/ATM1/ATM1/Program.cs) (Startup and schema), [`ATM1/ATM1/Customer.cs`](https://github.com/axb2002/guichetatm/blob/main/ATM1/ATM1/Customer.cs) (Customer access), [`ATM1/ATM1/Form1.cs`](https://github.com/axb2002/guichetatm/blob/main/ATM1/ATM1/Form1.cs) (Login screen), [`ATM1/ATM1/MainMenu.cs`](https://github.com/axb2002/guichetatm/blob/main/ATM1/ATM1/MainMenu.cs) (Main menu)
