Commenting - GCSE Computer Science Definition

In the context of GCSE Computer Science, "commenting" refers to the practice of adding explanatory notes within the code of a computer program. These comments are written by programmers to describe the purpose and functionality of specific sections or lines of code, without affecting the actual execution of the program. Comments serve as an important tool for improving code readability and maintainability, making it easier for both the original programmer and others to understand, modify, and debug the program in the future. In most programming languages, comments are marked by specific symbols or notations, such as a double forward slash (//) in Python or Java, or a hash (#) in Python.
