Answer 2

In the Switch statement, two case constants in the same switch can have identical values is incorrect

Switch statement

• A switch statement allows a variable to be compared against a list of values for equality.
• The switch expression must be of an integer or character type and the case value must be an integer or character constant.
• The switch statement allows us to execute multiple operations for the different possible values of a single variable, which is cumbersome in nested ifs.
• It is permissible to nest switch statements.

However, no two constant-expression values within the same switch statement can have the same value.
