FAQs on #3.1 Kotlin Basic Syntax Tutorial: COMMENTS Part-1 Video Lecture - Kotlin Tutorial for Beginners: Learn Kotlin in easy language - Back-End Programming

1. What is the purpose of comments in Kotlin programming?
Ans. Comments in Kotlin programming are used to provide additional information or explanation about the code to other developers or to oneself. They are ignored by the compiler and have no impact on the execution of the program.
2. How are single-line comments written in Kotlin?
Ans. Single-line comments in Kotlin are written using two forward slashes (//) followed by the comment text. Everything after the // on the same line is considered a comment and is ignored by the compiler.
3. Can multi-line comments be used in Kotlin? If yes, how are they written?
Ans. Yes, multi-line comments can be used in Kotlin. They are written by enclosing the comment text between /* and */. Anything between these two symbols, even if it spans across multiple lines, is considered a comment and is not executed by the compiler.
4. Are comments important in programming?
Ans. Yes, comments are important in programming as they help in improving code readability and understanding. They allow developers to explain the purpose of code, provide insights into complex algorithms, or document any important information related to the code. Comments make it easier for other developers to collaborate and maintain the codebase.
5. Should comments be used excessively in Kotlin programming?
Ans. No, comments should not be used excessively in Kotlin programming. While comments are helpful, it is recommended to write code that is self-explanatory and easy to understand without relying heavily on comments. It is best to use comments sparingly and only when they add value by providing additional information that cannot be easily inferred from the code itself.
