Learn C# Console Application Basics:

Math and Area Calculations

C# is a powerful programming language that allows developers to build a wide range of applications. In this article, we will explore how to create a simple C# console application that performs basic mathematical operations and calculates the area of various shapes. Whether you are a novice programmer or just getting started with C#, this step-by-step guide will help you understand the fundamentals of console-based application development. If you haven't read our first article on C# programming you can read it here.

Prerequisites:

Before we begin, make sure you have the following set up on your system:

A C# development environment, such as Visual Studio or Visual Studio Code, installed on your computer.

Getting Started:

Open your C# development environment, create a new project, and choose "Console Application" as the project template.

Once the project is created, you will see a file named "Program.cs." This is where you will write your C# code.

Performing Basic Mathematical Operations:

Let's start by implementing some basic mathematical operations, such as addition, subtraction, multiplication, and division. Replace the content of the "Main" method with the following code:

Save the changes and run the program. Now you can enter two numbers, and the program will display the results of the mathematical operations.

Calculating Area of Shapes:

Next, let's implement the area calculation for basic shapes like a rectangle, circle, and triangle. Add the following code to the existing program:

Save the changes and run the program again. You can now calculate the area of the rectangle, circle, and also the triangle by providing the required dimensions.

Congratulations! You have successfully created a C# console application that performs basic mathematical operations and also calculates the area of different shapes. This introductory project should help you understand the fundamentals of C# programming and console-based application development. From here, you can explore more advanced concepts and functionalities to build even more sophisticated applications. Happy coding!
