True
Break statements are used when you want your program flow to come out of the switch body.
True
The default case can be used for performing a task when none of the cases is true.

True
In switch, if there is a match, the associated block of code is executed
True
A break can save a lot of execution time because it “ignores” the execution of all the rest of the code in the switch block.

False curly brackets is the right answer.
The constant-expression for a case may be a floating point number.
False
In switch, the value of the expression is compared with the values of each case.
True

True
Each case is followed by the value to be compared to and a semicolon.
True
The break statement causes an exit ________.
Innermost loop or switch
Nested switch statements should be avoided as it makes program more complex and less readable.
