How To Add A Comment.¶

Objective¶

Learn how to add a comment in the code.

Requirement¶

Adding comments is a very handy way of adding documentation to your code, it serves as a tool to let others know what you have written and makes navigating your code an easy task.

Go has a specific format for adding comments and recommends adding comments wherever it makes sense.

Code¶

Adding a comment is pretty easy

// This is a comment

The compiler ignores the comment and runs your code, however as humans for us to remmember what we have written and for others to understand writing comments would make sense.

4 // Importing the package "fmt"

6
7 // Declaring the main function
8 func main() {
9
10 // Printing Hello World to the standard output
11 fmt.Println("Hello, World!")
12 }
13 // main function ends
