Create a class called calendar which contains the following:
A month, which is an integer from 1 to 12.
A day, which is an integer from 1 to 31.
A year, which is an integer representing the year from 0 onward.

Create a class called history which contains the following:
A string which holds the information about the event.
An a calendar object, which holds the date the event took place.

You are only required to use public variables.

Write a program that has an array of 5 history objects.
In the program, define 5 events from world history.

Have the program print out the 5 events using a function called
print_history. This function will receive a history object to
work on.

Use a loop to call the print_history function 5 times, each time passing
a different event to print.
