(Find the number of days in a month) Write a program that prompts the user to enter the month and year and displays the number of days in the month. For example, if the user entered month 2 and year 2012 , the program should display that February 2012 had 29 days. If the user entered month 3 and year $2015,$ the program should display that March 2015 had 31 days.

Key Concepts

Leap Year Calculation

This concept involves determining whether a given year is a leap year. The general rule is that a year is a leap year if it is divisible by 4, except for years that are divisible by 100, unless they are also divisible by 400. This calculation affects the number of days in February and is a critical part of date and time programming.

Conditional Statements

Conditional statements, such as if-else structures or switch-case cases, are used to execute different blocks of code based on certain conditions. In this problem, they are necessary for determining the correct number of days in a month based on both the month value and leap year status for February.

Mapping Month to Number of Days

This concept involves associating each month with its corresponding number of days. Typically, most months have fixed lengths: 30 or 31 days, except February, which varies between 28 and 29 days depending on leap year status. Implementing this mapping is fundamental in calendar-related programming problems.

User Input/Output Handling

Handling user input and producing the appropriate output are essential in interactive programs. The program must accurately capture the user-provided month and year values, process them according to the logic (including the leap year logic), and then display the result in a clear, formatted message.
