VB.NET Calculator Application: Foundations in Programming Assignment 1

This assignment showcases the practical implementation of a calculator application developed in VB.NET using Visual Studio. It covers essential calculator functionalities such as addition, subtraction, multiplication, division, clear, and backspace operations, illustrated with screenshots of the application's interface and results. The assignment also includes a discussion on arrays in VB.NET, explaining how one-dimensional and two-dimensional arrays are declared and initialized, with code examples provided. The report details the step-by-step process of creating the calculator application and demonstrates the use of arrays in VB.NET, offering a comprehensive guide for students learning VB.NET programming. Desklib provides access to this assignment and many other solved assignments and past papers to help students excel in their studies.

Introduction
This assignment is based on VB.NET. There are two questions in this assignment. The
first question is based on creating a web application of calculator. The application is
generated in programming language VB.NET using visual studio IDE. In second
question the discussion will be made on arrays. In VB.NET how arrays and
multidimensional arrays are created. The report briefly discussed the practical
implementation of calculator application.
