High-level programming languages: What is the principal advantage profile of high-level languages compared to low-level coding?
-
AFewer people, less management and shorter transition in learning time
-
BImproved debugging capability, and superior documentation
-
CA greater degree of machine independence
-
DAll of the above
-
ENone of the above
Answer
Correct Answer: All of the above
Explanation
Introduction / Context:Choosing an implementation level affects productivity, maintainability, and portability. High-level languages (HLLs) abstract hardware details, enabling faster development and easier maintenance than assembly or microcode for most applications.
Given Data / Assumptions:
- We compare high-level languages to lower-level alternatives.
- We value debugging tools, documentation clarity, and portability.
- We assume modern compilers and development environments.
Concept / Approach:HLLs provide richer syntax, type systems, libraries, and tooling (IDEs, debuggers, linters). They reduce cognitive overhead and are generally machine-independent, targeting multiple architectures through compilers or virtual machines. This typically shortens onboarding and reduces the number of specialists required per feature delivered.
Step-by-Step Solution:
Evaluate the benefits listed: team scaling (fewer people), learning curve, debugging, documentation, and machine independence.Map each benefit to HLL characteristics: abstractions improve readability and maintainability; standardized ecosystems support debugging and docs; compilers abstract ISA differences.Conclude that all listed advantages hold for HLLs in general practice.Choose the option that aggregates these benefits.Verification / Alternative check:Industry case studies and software engineering principles (e.g., cost of defects vs. abstraction level) support the claim that HLLs improve productivity and portability.
Why Other Options Are Wrong:Each individual statement is true, but the best answer encompasses them all; selecting a single item unnecessarily narrows the advantages.
Common Pitfalls:Believing performance trumps all; in most domains, HLLs deliver adequate performance with tremendous productivity gains.
Final Answer:All of the above
