Chapter 4: Problem 27

The expression that follows the switch statement must have a(n) ________ value.

Short Answer

Expert verified
Answer: Integer or discrete.

Step by step solution

01

Understanding the switch statement

A switch statement is a control structure used in programming to execute different blocks of code based on the value of a specific variable or expression. In most programming languages, the expression that follows the switch statement must have a value that is used to determine which block of code to execute.
02

Identifying the value type

The expression that follows the switch statement must have an "integer" or "discrete" value. This is because the switch statement compares the value of the expression to a set of constant integer values (referred to as "case" labels or values), and executes the block of code associated with the matching case value. Some programming languages, such as C# and Java, also allow the use of enumerated types or strings as the value, but the main principle remains the same - it should be discrete and comparable. So the correct answer for the blank is:
03

Completing the statement

The expression that follows the switch statement must have a(n) "integer or discrete" value.
