Language translation pipeline: is a compiler a translator that converts high-level language source code into a set of executable machine instructions (object code/binaries)?

Difficulty: Easy

Correct Answer: Applies

Explanation:


Introduction / Context:
Software moves from human-friendly forms to CPU-executable forms through translation tools. This question distinguishes the compiler’s role from assemblers and interpreters.



Given Data / Assumptions:

  • High-level languages include C, C++, Java (ahead-of-time), Rust, etc.
  • Compiler output may be object files needing linking into executables.
  • Target is machine code for a specified architecture (e.g., x86, ARM).
  • JIT compilers are special cases layered in runtime environments.


Concept / Approach:
A compiler parses high-level syntax, performs semantic analysis and optimization, and emits machine code or an intermediate object file that is later linked. The result is a binary executable or library that the CPU can run. This is distinct from an assembler (assembly → machine) and an interpreter (executes source or bytecode step-by-step without producing a final native binary ahead of time).



Step-by-Step Solution:

1) Source code is tokenized and parsed into an abstract syntax tree. 2) The compiler checks types, performs analysis/optimizations. 3) It generates machine code or intermediate representation, then object files. 4) A linker resolves symbols and produces the final executable binary.


Verification / Alternative check:
Build tools (e.g., gcc/clang) produce .o/.obj and then link to an .exe/.elf, demonstrating translation to machine code.



Why Other Options Are Wrong:
Does not apply: contradicts the role of a compiler. JIT is optional and not required. Assembly is translated by an assembler, not a high-level language compiler.



Common Pitfalls:
Confusing bytecode VMs with native compilation; equating “compiler” with “interpreter.”
