State whether each of the following is true or false. If false, explain why.

a) The default case is required in the switch selection statement.

b) The break statement is required in the last case of a switch selection statement.

c) The expression ((x > y) && (a < b)) is true if either x > y is true or a < b is true.

d) An expression containing the || operator is true if either or both of its operands are true.

e) The comma (,) formatting flag in a format specifier (e.g., %,20.2f) indicates that a value should be output with a grouping separator.

f) To test for a range of values in a switch statement, use a hyphen (–) between the start and end values of the range in a case label.

g) Listing cases consecutively with no statements between them enables the cases to per- form the same set of statements.
