Write a C++ program that will prompt the user to enter a year and produce a calendar for that year. Do not forget that years that are divisible by 4 but not divisible by 100 unless they are divisible by 400 are leap years.

The first day of the year can be calculated using the following formula:

W = ((29 - 2*C + y + y/4 + C/4)%7 + 7) % 7

where

• Y is the year

• C = (Y-1) / 100, the century

• y = (Y-1) % 100

• / denotes the integer division

• % denotes the integer remainder (mod)

• W is the week day (0=Sunday, ..., 6=Saturday)

• only iostream iomanip and windows.h libraries are allowed.
