Challenge: Declaring & Using Constants

Task

Swipe to start coding

You're building a subscription management system for a new streaming service. The program calculates the totalCost of the subscription based on the number of devices the user has (userDevice) and a fixed monthly price:

Declare a constant called MONTHLY_PRICE which stores the value 9.99.

Note

In most programming languages, constants are typically written in all uppercase letters, with words separated by underscores (_). This naming convention helps differentiate constants from regular variables and makes them easily recognizable in the code.
