Write a program to input two valid dates, each comprising of Day (2 digits), Month (2 digits) and Year (4 digits) and calculate the days elapsed between both the dates.

Test your program for the following data values:

(a)
FIRST DATE:
Day: 24
Month: 09
Year: 1960

SECOND DATE:
Day: 08
Month: 12
Year: 1852

Output: xxxxxxxx
(these are actual number of days elapsed)

(b)
FIRST DATE:
Day: 10
Month: 01
Year: 1952

SECOND DATE:
Day: 16
Month: 10
Year: 1952

Output: xxxxxxxx
(these are actual number of days elapsed)
