No its not compulsory, had it been compulsory compiler would have been desined not to allow multiple cases without break. However care needs to be taken to put break after every cases. There can always be a case when we may not require break after all cases.

switch executes everything from the matched case until a break is encountered

it is compulsory because you do not use break after every case this will happen suppose you have 3 cases case 1 ...case 3. like that if the user input a choice related to case when then of course as you know it will execute case 1 but remember you have not used break statement so after the execution of first case all the cases below that case 1will automatically be executed so it will generate a kind of logical or syntax error

yes otherwise the all the cases following after "selected" case will be executed also you don't have to put break in the default case because it is the last case.
