What is meant by creating a custom exception type in code?

Creating a custom exception type in code means defining a user-defined exception class that inherits from a base exception class (for example, in C# from Exception). This allows for creating more specific and informative errors that can be handled separately from standard ones.

Advantages:

• Clear classification of errors
• Ability to add additional properties and methods
• Improved readability and maintainability of code

Example in C#:

public class MyCustomException : Exception
{
    public MyCustomException(string message) : base(message) {}
}

// Usage
throw new MyCustomException("A specific error occurred");

This approach helps to better control error handling in the application.
