Break statement in the default case

Still new to C++ and its unique syntaxes, I'm wondering if it makes any difference with or without the break statement switch (number) { case n: break; default: break; // or not }

If the number parameter provided isn't one of the cases, default is called. If there's no default and no match you'll get unexpected output.

No, cause it's the final case and will break regardless. It just let's everybody know for sure.

Adding to Slick, You'd still need the `break` IF the `default` case is placed in other slot but the last.

switch (emotion){ case 1: System.out.println("You are happy!"); break; case 2: System.out.println("You are sad!"); break; case 3: System.out.println("You are angry"); break; case 4: System.out.println("You are surprised"); break; default: if (emotion > 4 || emotion <1 ){ System.out.println("Unknown emotion."); } } }
