Question: 1 / 400

What does the StringBuilder class allow you to do?

Create immutable strings

Represent mutable strings

The StringBuilder class is specifically designed for situations where you need a mutable string representation. This means you can modify the string content without creating a new instance each time. The class allows for efficient appending, inserting, removing, and replacing of characters within the string, which is particularly useful in scenarios where performance is critical, such as in loops or when manipulating large amounts of text.

In contrast, immutable strings, as noted in the first option, cannot be changed after being created, which is the standard behavior of the String class in .NET. While string comparisons and splitting strings are important operations, they are not the primary functions of the StringBuilder class. The main advantage of using StringBuilder is its ability to manage and manipulate string data dynamically and efficiently.
