Necessary??

Question

in c#, is it necessary default case have break keyword??

Answer 1

This is not C# syntax, but anyway: If you close your program, how should the compiler check, if your case ends with a break statement? That doesn't really make sense to me.

Answer 2

You need one of these statements at the end of each case: break, goto, return or throw
It is mandatory to have one of this statements on each case, even for the default case.

Answer 3

No need

Answer 4

case 1:
exit(0);

why this is not required break keyword?
