Why do you put break in each case in switch?
The break keyword in each case indicates the end of a particular case. If we do not put the break in each case then even though the specific case is executed, the switch will continue to execute all the cases until the end is reached. This should not happen; hence we always have to put break keyword in each case.
How does a break statement in a switch statement work?
In a switch statement, the break statement causes the program to execute the next statement outside the switch statement. Without a break statement, every statement from the matched case label to the end of the switch statement, including the default clause, is executed. In loops, the break statement ends execution…
When does control go out of the switch?
As soon as a case is found the block of statements associated with that particular case is executed and control goes out of the switch. The break keyword in each case indicates the end of a particular case.
Do we need the break in default for switch?

Can a C # switch statement take a break?
C# switch statements definitely allow for it (check the 3rd example), hence the need for break. @DanielB Yes we are, but the compiler won’t allow a condition, code, and then another condition without a break. You can have mutliple conditions stacked with no code between, or you need a break.
When to introduce a break statement in C?
When working with switch case in C, you group multiple cases with unique labels. You need to introduce a break statement in each case to branch at the end of a switch statement. The optional default case runs when no other matches are made.
