and surface are of a sphere.

Submit the .cpp source
code file(s) on Ecampus.

*
Extra Credit (difficult):* If you include time.h, you can get the number
of seconds that have elapsed since Jan. 1, 1970 using time(NULL).
Write a program that calculates the current date and time using this
number. You cannot use any other functions other than time(NULL).
