How do subroutines contribute to better organization in ARM assembly programming?

easy📝 Conceptual Q1 of 15
ARM Architecture - Subroutines and Stack
How do subroutines contribute to better organization in ARM assembly programming?
ABy making the code run faster without changes
BBy increasing the size of the codebase
CBy allowing repeated code to be written once and reused
DBy eliminating the need for registers
Step-by-Step Solution
Solution:

  1. Step 1: Understand subroutine purpose

    Subroutines encapsulate code blocks for reuse.

  2. Step 2: Recognize code reuse benefit

    Writing code once and calling it multiple times reduces duplication.

  3. Final Answer:

    By allowing repeated code to be written once and reused -> Option C

  4. Quick Check:

    Code reuse improves organization [OK]
Quick Trick: Subroutines enable code reuse and organization [OK]
Common Mistakes:
  • Thinking subroutines speed up code automatically
  • Assuming subroutines remove the need for registers
