Challenge: Rectangle Area Calculator
Challenge Overview:
You will create a function to calculate the area of a rectangle. The function must throw a custom exception, NegativeDimensionException, if either the width or the height provided is negative. This ensures that only valid, non-negative dimensions are used in area calculations.
Key Points:
- Define a custom exception class:
NegativeDimensionException; - Calculate the area using width and height;
- Throw the exception if width or height is negative;
- Return the area for valid dimensions.
Example Usage:
try {
int area = rectangleArea(5, -2);
// This line will not execute because an exception is thrown
} catch (const NegativeDimensionException& e) {
std::cout << e.what() << std::endl; // Output: Rectangle dimensions must be non-negative.
}

Create a function that calculates the area of a rectangle, ensuring both dimensions are valid.
Your task:
- Write a function that returns the area of a rectangle using the provided width and height;
- If either dimension is negative, throw a custom exception to prevent invalid area calculations;
- Use a custom exception class with a clear error message to indicate the problem.
Follow these requirements:
- Define a custom exception class for negative dimensions;
- Implement the area calculation function;
- Throw the exception if any dimension is negative;
- Return the calculated area if both dimensions are valid.

Can you show me how to define the NegativeDimensionException class?
How should the rectangleArea function be implemented?
What should the exception message say when thrown?
Awesome!
