Commenting out code is a handy technique used by programmers for debugging or editing code. It involves disabling one or more lines of code temporarily so that it can be skipped during execution. This technique can help locate bugs and fix code issues.
Why Commenting is Important
Adding comments to computer programs is crucial for proper code maintenance. It inserts much-needed human-readable details that explains precisely what the code does. Commenting helps locate bugs faster, allowing programmers to quickly fix errors. Proper use of comments can make the code maintenance process simpler and smoother.
How to Comment Out Code
Commenting out code can be done in many ways depending on the programming language in use. Here are some of the basic methods:
- Single-line commenting: This involves using a specific symbol – // for commenting out a single line. The symbol indicates that the code after it should be skipped when running the program.
- Multi-line commenting: This method is used when commenting out several lines of code at once. Usually, the symbol /* is placed at the beginning of the lines to be commented out, and the symbol */ is inserted at the end of the code block.
