Self Doubt

Question

In the switch statement, if we write default case above all then will it be executed?

a = 2;

switch(a){

default : print("abc");

case 2 : print("xyz");

}

what will be the o/p ?

Comments

default can be written anywhere in the switch.here the o/p will be xyz only...

Answer 1

Case and the default clause can occur in any order. And default clause is also optional. According to your program output will be "xyz"

Since there is no break statement, will the control even find case 2?

---

Yes, bcoz break is used to exit from the switch and since there is no break, so control will flow from top to bottom.

Alright, thanks @vishalshrm539!

Answer 2

If the switch matches with some case, then the default will not be executed. (provided every case has its break statement )

but if none of the cases matches with switch variable then the default will be executed.

In this case, you have the default in the top and with no break statement. That will cause case 2 to execute also.

Here output will be xyz because case is matched.

but if a=3, then output will be abcxyz

Everything is right but your first statement is false in one situation.

If one case gets matched then all other subsequent cases(including Default) will be executed without looking at their case values provided there are no breaks in between.

Yeah true, but it is legit to use break statements after every case. thanks though, edited.
