Comments in programming play a crucial role in enhancing the readability and maintainability of the code. They help other programmers—and the original author when revisiting the code later—understand the purpose and functionality of different parts of the code. This is especially important in collaborative environments where multiple developers may work on the same codebase, as well as in long-term projects where the initial context may be forgotten over time. By providing insights and explanations, comments assist in clarifying complex code segments or logic, ultimately making it easier to modify and expand the program in the future.

Although comments do not affect the execution speed of the code, nor do they automatically document the code or serve exclusively as reminders for the programmer, they offer significant value through the context and clarity they provide. Good commenting practices contribute to the overall quality and maintainability of software projects, which is why emphasizing their importance is essential for any programmer.
