Difficulty: Hard
About this MCQ
This Hard Compiler Design MCQ checks one syllabus fact.
The question is: “Identify the correct definition of Code optimization.”
The accepted answer is A. The compiler phase that improves intermediate or final code to make it run faster or use fewer resources.. Identify the correct definition of Code optimization is answered by The compiler phase that improves intermediate or final code to make it run faster or use fewer resources option A Option B A program that executes source code directly translating and running it line by line without producing a separate executable does not match the stem it is a near-miss used to catch incomplete recall of The compiler phase that improves intermediate or final code to make it run faster or use fewer resources Option C A program that translates an entire source program written in a high-level language into machine code before execution does not match the stem it is a near-miss used to catch incomplete recall of The.
- A. The compiler phase that improves intermediate or final code to make it run faster or use fewer resources. ✓
- B. A program that executes source code directly, translating and running it line by line without producing a separate executable.
Why not B: “A program that executes source code directly, translating and running it line by line without producing a separate executable.” is not correct. The accepted answer is A. The compiler phase that improves intermediate or final code to make it run faster or use fewer resources.. Identify the correct definition of Code optimization is answered by The compiler phase that improves intermediate or final code to make it run faster or use fewer resources option
- C. A program that translates an entire source program written in a high-level language into machine code before execution.
Why not C: “A program that translates an entire source program written in a high-level language into machine code before execution.” is not correct. The accepted answer is A. The compiler phase that improves intermediate or final code to make it run faster or use fewer resources.. Identify the correct definition of Code optimization is answered by The compiler phase that improves intermediate or final code to make it run faster or use fewer resources option
- D. The first phase of compilation that converts source code into a sequence of tokens.
Why not D: “The first phase of compilation that converts source code into a sequence of tokens.” is not correct. The accepted answer is A. The compiler phase that improves intermediate or final code to make it run faster or use fewer resources.. Identify the correct definition of Code optimization is answered by The compiler phase that improves intermediate or final code to make it run faster or use fewer resources option
Correct answer
A. The compiler phase that improves intermediate or final code to make it run faster or use fewer resources.
