Should we break the default case in switch statement?

Question

Assuming this example code (source):

#include 

void playgame()
{
    printf( \"Play game called\" );
}
void loadgame()
{
    printf( \"Load g

Break Seems to Be Optional

break seems to be optional in that case. and also your code will work almost fine.

However

in many situations adding break improves your code and protect your code from errors/exceptions.

it increases readability, consistency and more error free.

some language like C# break(or other control-flow statement that exits the case) is technically needed after the last alternative. dan04

so for better programming practices i suggest one should use it.

see this excellent post for more details.
