In Kotlin, you can add comments to your code using two different syntaxes: single-line comments and block comments.
Single-line comments start with two slashes (//) and continue until the end of the line:
// This is a single-line comment
val x = 5 // You can also add a comment at the end of a line of code
Block comments start with a slash and an asterisk (/*) and end with an asterisk and a slash (*/). Block comments can span multiple lines of code:
/*
This is a block comment.
It can span multiple lines of code.
*/
val y = 10
It’s a good practice to add comments to your code to explain what it does, why it does it, and any other relevant information. This can make your code more understandable and maintainable for yourself and others who may read it in the future.
