Question

The controlling expression for a switch statement includes all of the following types except:

a) Integer
b) Float
c) String
d) Boolean

Answer 1

The controlling expression for a switch statement cannot include the float data type, as switch statements require exact matches, which floats cannot reliably provide.

Step-by-step explanation:

The controlling expression for a switch statement can include several data types, but there is one that is not accepted. The types that can be used include integer values, string literals, and boolean values in some programming languages. However, the float type is typically not allowed because switch statements require discrete values that can be matched exactly, and floats, with their fractional components and issues with precision, are not well-suited for this.
