Question

Write a program named CheckMonth2 that prompts a user to enter a birth month and day.

Display an error message that says Invalid date if the month is invalid (not 1 through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between 1 and 29 for February).

If the month and day are valid, display them with a message. For example, if the month entered is 2, and the day entered is 17, the output should be 2/17 is a valid birthday.

//Display an error message if the month is invalid (not 1 through 12)
//or the day is invalid for the month
//If the month and day are valid, display them with a message.
