Question

Which of the following is not a reason to include comments in programs?

a) To explain complex logic
b) To make the program run faster
c) To aid in understanding
d) To document for future reference

Answer 1

Comments in programs serve multiple purposes: explaining complex logic, aiding in understanding, and documenting for future reference. Making the program run faster is not a reason to include comments.

Step-by-step explanation:

Comments in programs are used for several reasons:

1. To explain complex logic: Comments can be used to provide explanations and clarifications for complex sections of code, helping other programmers understand the intention and purpose behind the code.
2. To aid in understanding: Comments can be used to provide a high-level overview of a program or specific sections, making it easier for other programmers (or even the original programmer) to understand the code and its functionality.
3. To document for future reference: Comments can serve as a form of documentation, providing details about the code's purpose, its inputs and outputs, and any assumptions or constraints. This can be helpful for future maintenance and debugging.

Making the program run faster is not a reason to include comments in programs. Comments do not affect the runtime or execution speed of a program.
