//Program Explanation//

///////////////////////

In this program simple we are using cout and cin.

cout is used for output and cin used for input.

year=input/365 will divide your input by 365 and save the quotient in year

days=input%365 will save the remainder of input/365

month=days/30 will divide your input by 30 and save the quotient in month

days=days%30 will save the remainder of days/30
