Sample C++ code that has an output of calendar

Write a program, that incorporates a function called no_in_month that will return the
number of days (an int not a string) in the month of February. The year is input by the
user in main() and passed to the function when it is called. A leap year (29 days in
February) occurs if the year is evenly divisible by 4. However, leap years do not occur at
the end of centuries which are not evenly divisible by 400, e.g. the years 1700, 1800,
1900 are not leap years but 1600, 2000 are. Check your output for various years. (To
check calendars, see http://www.timeanddate.com/calendar/ but change the country to
Spain as Spain was one of the earliest countries to adopt the (Gregorian) calendar we use
today. The calendars shown on this site are with Monday as the first day of week. Use
the option to change to Sunday to avoid confusion later.) hi is there any easy way of doing this
