How do you break a while loop in a switch case?
Use the continue statement to finish each case label where you want the loop to continue and use the break statement to finish case labels that should terminate the loop. Of course this solution only works if there is no additional code to execute after the switch statement.
What does the break do inside of a loop?
When a break statement is encountered inside a loop, the loop is immediately terminated and the program control resumes at the next statement following the loop. It can be used to terminate a case in the switch statement (covered in the next chapter).
Can we write continue in switch case?
We can not use a continue with the switch statement. The break statement terminates the whole loop early. The continue statement brings the next iteration early.
Can we use while inside switch?
Points to remember while using Switch Case There can be any number of case statements within a switch. Each case is followed by the value to be compared to and after that a colon.

How to break out of a foreach loop?

Is it possible to break out of an outer loop?
You can’t easily break out of the outer loop, but you can continue it. If you reverse your logic then you get this. Note there is a break immediately after the switch statement to exit the loop. This isn’t very readable code in my opinion, and I think a flag is still best.
When to use a break in a switch block?
Normally, you use break but if you use a break within a switch block it will just get you out of a switch block and the foreach loop will continue execution:
