Introduction The process of creating computer program code has changed considerably since the early days of computer science, when the first programs were written directly in binary using punch cards.
Integrated Development Environment (IDE): software that helps programmers to design, create and test program code.
LE
Today we use high-level programming languages. These languages use coding statements that are close to human language. The code statements are then translated to binary before being executed by the computer. The majority of high-level programming is completed using an Integrated Development Environment (IDE), which provides the programmer with tools that help create, debug and translate the programs. Visual Studio 2019 Community is an IDE that helps to generate programs written using the Visual Basic programming language.
KEY WORD
1.1 Getting Visual Studio 2019 Community for Windows
P
Visual Studio 2019 Community is the current version of free developer tools provided by Microsoft. The IDE supports a wide range of programming languages including Visual Basic, Visual C++ and Visual C#. Visual Basic provides an interface that allows students to develop programming skills while at the same time producing satisfying systems.

Visual Basic also provides programmers with access to a large class library. Classes are templates that hold prewritten code that support functionality of objects. As your skills increase, you will be able to use this feature-rich development environment to produce and publish complex systems. System requirements and download options can be found on the Microsoft website by searching ‘Visual Studio downloads’.
KEY WORDS
Visual Studio 2019 Community: a version of the Integrated Development Environment (IDE) produced by Microsoft used to create programs using the Visual Basic programming language.
interface: the way in which a user inputs data into and receives information from a computer system. classes: templates that hold prewritten code which supports the functionality of objects. All of the GUI elements in Visual Basic are objects of a class. The GUI objects can be created and manipulated without the need to write code as the code required is already contained in the class.
