What is an auto-implemented property in C#?

1. A property that cannot be altered

2. A shorthand syntax for property declaration

3. A property with private backing fields only

4. A property that uses interfaces

The correct answer is: A shorthand syntax for property declaration

An auto-implemented property in C# is indeed a shorthand syntax for property declaration. This feature simplifies the coding process by allowing developers to define a property without having to explicitly create a private backing field. When you use an auto-implemented property, the compiler automatically generates the necessary backing field for you. For example, instead of writing out a complete property with a backing field, you can declare a property like this: ```csharp public string Name { get; set; } ``` In this case, you are essentially telling the compiler to create a private field behind the scenes to hold the value of the `Name` property. This reduces boilerplate code and makes the code more readable, allowing developers to focus on higher-level logic instead of lower-level implementation details. In contrast, the other options do not accurately describe auto-implemented properties. A property that cannot be altered does not refer to auto-implemented properties specifically, as these properties can be set and retrieved. A property with private backing fields only isn't a defining characteristic of auto-implemented properties, since these fields are created automatically by the compiler, and thus are not explicitly defined by the developer. Lastly, while properties can be part of interfaces, this is not a unique quality of auto-
