DAY AND TIME

• Problem Description

  
  Define a structure date containing three integers -day,months and year. Write a program using functions to read data, to validate the data entered by the user and then print the date on the screen. 
  
  For example,if you enter 31/6/2007 is invalid as June does not has 31 days, similarly if you enter 25/13/2000 then it is invalid month as month ends with 12(1-12. jan to dec). The threshold value for year is 3000 (Invalid Year). Valid year: 0000-2999
  
  Using the structure definition of the above program, write a function to increment that .Make sure that the incremented date is a valid date. Modify the above program to add a specific number of days to the given date.Write a function to compare two date variable.
  
  Output:
  33 12 1989 - Invalid Day
  31 12 3000 - Invalid Year
  31 13 1989 - Invalid Month
  25 12 1989- New Date=26 12 1989
  
  Mandatory:
  
  1. Create a Structure as "Date"
  
  2. Create three data members as date(int), month(int), year(int)
  
  3. The structure variable for "Date" structure is "D"
  
  Note: The structure variables, data members and structure name are CASE Sensitive.
  
  Follow the same case mentioned in the mandatory
