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         


        

Answer 1

It depends on How default case is written.

In the following case break is neccessary.

switch ( input ) {
         default:
            printf( "Bad input, quitting!\n" );
            break;
        case 1:            /* Note the colon, not a semicolon */
            playgame();
            break;
        case 2:
            loadgame();
            break;
