## Overview

This is a Windows Forms educational application for numerical tabulation and array/math lab exercises. The visible entry point opens the tabulation form; its menu exposes one-dimensional arrays, two-dimensional arrays, and three Lab 2 tasks. The two-dimensional form demonstrably delegates duplicate and minimum calculations to its array helper. Other forms and their event-handler wiring were not sampled, so those interactions are represented as capabilities without inferred call edges.

Main entry points: [`lab1/Program.cs`](https://github.com/icesun39/lab1_dotnet/blob/master/lab1/Program.cs) (Application entry), [`lab1/lab1/twodim_array/Form_twodimen_array.cs`](https://github.com/icesun39/lab1_dotnet/blob/master/lab1/lab1/twodim_array/Form_twodimen_array.cs) (Two-dimensional form), [`lab1/lab1/tabulate/Form_tabulate.cs`](https://github.com/icesun39/lab1_dotnet/blob/master/lab1/lab1/tabulate/Form_tabulate.cs) (Tabulation form), [`lab1/lab1/onedim_array/Form_onedimen_array.cs`](https://github.com/icesun39/lab1_dotnet/blob/master/lab1/lab1/onedim_array/Form_onedimen_array.cs) (One-dimensional form)
