C# is one of the most popular programming languages in the world, and its latest stable version, C# 10, has several new features and updates that make it an excellent choice for a wide variety of applications. Combined with the .NET framework, C# can empower developers to build native applications for all the major consumer operating systems as well as the cloud.

The course starts with an introduction to programming concepts such as conditional statements, loops, arrays, and functions. You’ll explore advanced topics of object-oriented programming (OOP) including classes, inheritance, access, and extensions. Finally, you’ll work with data structures, events, concurrency, testing, and databases.

By the end of this course, you’ll have a working knowledge of not only the C# programming language, but also key ideas of software engineering. You’ll also be prepared to build and deploy native applications with the .NET framework.

## What is a ```StringBuilder```?
When a string's value is changed, a new string object is created in memory. This is because a string is *immutable* (it can't be changed once created). This uses additional system resources. A **StringBuilder** is a *mutable* string-like object whose value changes based on the sequence of characters (a new string object in memory isn't created when appended).

To use a `StringBuilder`, include the `using` statement:
```C#
using System.Text;
```

## Instantiate a ```StringBuilder```

In the example below, an object of `StringBuilder` is created.
