When you don't use break, all cases after first case which was execuded will be executed, for example: a = 1; switch(a) { case 0: print(0); case 1: print(1); case 2: print(2); default: print(3); } In this pseudocode 123 will be printed.

C# compiler raises error if you don't use break. But it allows you to use multiple cases in a row with single body. This is not allowed: switch(a) { case 0: print(0); case 1: print(1); case 2: print(2); default: print(3); } But this is allowed: switch(a) { case 0: case 1: case 2: print(2); break; default: print(3); break; } It will print 2 if a will be 0, 1 or 2

yes, because if you don't you may get unexpected results or error.
