About this MCQ

This Hard Compiler Design MCQ checks one syllabus fact.

The question is: “What is the function or purpose of Cross-compiler?”

The accepted answer is D. A compiler capable of creating executable code for a platform other than the one on which the compiler itself runs.. A compiler capable of creating executable code for a platform other than the one on which the compiler itself runs is the fact required by What is the function or purpose of Cross-compiler option D Option A A technique that compiles code into machine instructions at runtime rather than before execution does not match the stem it is a near-miss used to catch incomplete recall of A compiler capable of creating executable code for a platform other than the one on which the compiler itself runs Option B The use of regular expressions by a lexical analyzer to define and recognize valid tokens does not match the stem it is a near-miss used to catch incomplete recall of A compiler.

A. A technique that compiles code into machine instructions at runtime rather than before execution.
