b) two case constants in the same switch can have identical values

Answer 2

Option (b) two case constants in the same switch can have identical values is an incorrect statement.

Explanation:

• A switch statement allows you to compare a variable to a list of values for equality. Each value is referred to as a case, and each case is examined separately.
• A multi-way branch statement is a switch statement. It makes it simple to delegate execution to different areas of the program based on the expression's value.
• Duplicate case values aren't permitted in Switch statements. Two case constants in the same switch should not have the same value. A compile-time error occurs when a value is duplicated.
