Class called Date

sljackson36 (3)
I can't get my output to show the correct date, when I put in a date such as 10 10 1977 it shows 1/1/1977,January 1 1977, 1 January 1977

  /*I will design a class called Date that has integer data members to store month, day, and year. 
The class will have a 3-parameter default constructor that allows the date to be set at the time
a new Date object is created.  If the user creates a Date object without passing any arguments, 
or if any of the values passed are invalid, the default values of 1, 1, 2001(Jan. 1, 2001) should
be used.  I will demonstrate the class by a program that uses it.*/

Try to run it in C++ shell which appears at top-right corner of your code ..

Hi,

Nothing to do with your problem, but you shouldn't have to re-declare your monthname array, make it a member of your class, and remove it from main()

Good luck !!

Edit:

If you use an initializer list in the constructor, then you wont need the set functions either.

And your default constructor shouldn't initialize to 0's, you specified 1,1,2001

Do you check for feb 30, or months that only have 30 days, but the user input 31?

Cheers
