c$++$ Write a method$/$function called daysInMonth$()$ that takes in a month $($as an integer$)$ and an integer year as parameters and returns the number of days in that month as an integer. For example the call daysInMonth$(1,2000)$ should return $31$ as there are $31$ days in January$(1).$

If the user inputs a day in Feburary $(2)$ make sure to account for the possibility of a leap year.

Rules for leap years are:

If a year is divisible by $100,$ it must also be divisible by $400$ to be a leap year. For example, $1600$ is a leap year and $1800$ is not a leap year.

If a year is not divisible by $100$ it must be divisible by $4$ to be a leap year. For example, $2024$ is a leap year and $2025$ is not a leap year.

If the user types in a month that doesn't exist return $(-1)$ as an error message. Do the same for any year that is less than $0.$

After you have written the method, write a main program that demonstrates the use of your method in at least $4$ different ways showing that it works. Include at least one error case.

Hint: Using a switch$-$statement and its fall$-$through feature is much easier than using an if$/$else statement!
