I think it is compulsory because if we use break statement we will get proper output otherwise all the statements get executed.

Its not compulsory becouse when we want to prform same task for multiple cases in single itteration at that time there is no need use break statement for each case.
Eg:.
As + and - having same priority & * and / has same priority we can write.
Switch (operator).
Case +:.
Case -:.
Return 1;.
Break;.
Case *:.
Case /:.
Return 2;.
Break;.

If you not write it, it will ok, but all statements from other cases also get executed.
