Computer Science for IGCSE & O level - Algorithm Design And Problem Solving (Section 6 - No. 5)
What is the main benefit of using subroutines (or procedures) in an algorithm?
They always make the algorithm run faster.
They make the algorithm more complex.
They promote code reusability and organization.
They automatically fix any errors in the code.
Explanation
Subroutines promote code reuse, which improves the algorithm organization and understandability.
