and wiht :

in main func.

dayType e(obj.getMonth(), obj.getDay(), obj.getYear()); {obj.}

underline letter and characters make me trouble

Do you have a really old compiler?

I pasted all your code into a single file, and it seems to work.

It compiles OK as 1 file with VS2019. I've made a couple of small changes:

Enter number of days: 30

After increment date: 1-4-2021
Monday
Next day: Tuesday
Set Day: monday
Previous Day: Sunday
