Kotlin Programming By Example

Single-line comments

As the name implies, these comments span a single line. Single-line comments are started with two backslashes (//). Upon compilation of your program, all characters coming after these slashes are ignored. Consider the following code:

val b: Int = 957 // This is a single line comment// println(b)

The value held by b is never printed to the console because the function that performs the printing operation has been commented out.
