If the expression inside a switch evaluates to a floating-point number, it will be truncated to its integral part.a.Falseb.True

Breaking Down the Problem

1. Understand what happens when a floating-point number is evaluated inside a switch statement in programming languages that allow such constructs (like C, C++, Java).
2. Analyze the behavior of the switch case to determine if it indeed truncates the floating-point number to its integral part.

Relevant Concepts

• In programming languages, a switch statement is typically used to execute one block of code among many based on the value of a variable.
• When dealing with floating-point numbers, most languages (like C and Java) expect an integral type for the switch expression.

Analysis and Detail

1. Floating-point Evaluation: In languages like C++, Java, and C#, using a floating-point number directly in a switch statement is not allowed.
2. Truncation Behavior: While some explanations might imply that if it were allowed, the floating-point number would be truncated to its integral part, this is generally a misleading assumption since the conversion process usually leads to a compilation error.
3. Final Determination: Therefore, for practical scenarios, you cannot directly evaluate floating-point numbers in switches; the statement lead to a misunderstanding.

Verify and Summarize

Most programming languages will throw an error or warning if you directly use floating-point numbers in a switch statement. Therefore, the assertion that it will truncate to its integral part is not applicable in standard programming practice.

Final Answer

a. False
