Help to complete this birthday software?

ZahoorKhan (94)
I am creating a software in which if user gives his birthday like 12 March 2002 and this software will give day of his birth like Monday.
But I am stuck at a problem, when I enter birthday, this software skips everything and just go to at end statements Like "Do, you want to software again or not" and show nothing else why?
Here is output https://i.imgsafe.org/8ea94a9.png

show us your input

The problem is in your switch statement switch (ye_1)
If I enter 1965 for my year of birth ye_1 contains '1', but you don't handle it and so your program goes straight to line 307.

BTW. There is a much simpler solution for your task.

#Thomas1965 Why there is problem in switch (ye_1), because I am doing right.
User will either enter 19-- or 20-- so, ye_1 will either get 1 or 2. So we know all that we can use integers in Switch Statement.

But ye_1 and ye_2 are chars and they will never be equal to 1 or 2.
If you want to use char type you need to check for '1' and '2' in switch statement, not for 1 and 2.
Or just change their type to int.

char type can in fact be equal to 1 or 2, but in this case naaissus is right.
