What is the primary difference between an interpreter and a compiler in programming language execution?
Answer and explanation
Correct answer: D. both perform lexical syntax analysis concurrently without generating intermediate representations
- Step 1: Compilers (such as C/C++) produce standalone binary machine executables through scanning, parsing, and optimization stages. Step 2. Interpreters (such as standard Python or Ruby) analyze and execute program instructions interactively statement by statement. Answer: A compiler translates the entire source code into machine code prior to execution, whereas an interpreter executes source statements line-by-line. Why not the others: Compilers execute before runtime; interpreters execute during runtime; compilers detect syntax errors during compilation.
