The correct answer is Option 3: C, D, A, B, E.

Key Points

  • Code optimization is an important aspect of improving the efficiency and performance of code. The sequence provided in the correct answer represents a logical flow for optimizing code.
  • Redundant-instruction elimination (C) should be performed first. This step removes any unnecessary instructions, reducing the code size and improving its efficiency.
  • Flow of control optimization (D) follows. This step focuses on improving the control flow within the code, such as optimizing loops and conditional branches to make the code run faster.
  • Algebraic simplification (A) is the next step. This involves simplifying algebraic expressions within the code to make them more efficient and easier to compute.
  • Use of machine idioms (B) comes after. This step involves using specific machine-level instructions that are more efficient than their higher-level counterparts, which can improve the performance of the code on a given architecture.
  • Finally, improved target code (E) is generated. This involves producing the final optimized machine code that is more efficient and runs faster on the target machine.

Additional Information

  • Code optimization is typically performed by compilers, which can automate many of these steps to produce efficient machine code from higher-level programming languages.
  • The goals of code optimization include reducing the execution time, minimizing memory usage, and improving the overall performance of the software application.
  • Advanced optimization techniques may also consider factors such as power consumption and code maintainability.
  • Different optimization techniques may be more or less effective depending on the specific context and the nature of the code being optimized.
