Go Comments

 Go Comments

• In Go, comments are parts of the code that are ignored during execution.
• They are useful for explaining what the code does, which improves readability and makes maintenance easier.
• You can also use comments to temporarily disable parts of your code while testing or debugging.

Go provides two types of comments:

• Single-line comments: Start with //
• Multi-line comments: Enclosed between /* and */

Go Single-line Comments

• In Go, single-line comments begin with two forward slashes (//).

• Everything following // on that line is treated as a comment and is ignored by the compiler—it won't be executed as part of the program.

Example 1:

Package declaration
package main
// Importing the fmt package for formatted I/O
import "fmt"
func main() {
  // Printing a message to the console
  fmt.Println("Hello, World!")
}

Here's the rewritten version of your Go code example with a single-line comment at the end of a line:

Example 2:

package main

import "fmt"

func main() {

    fmt.Println("Hello, World!") // This comment explains the print statement

}

Let me know if you'd like the comment phrased differently or placed elsewhere.

Go Multi-line Comments (Rewritten)

• In Go, multi-line comments begin with /* and end with */.
• All text enclosed between /* and */ is treated as a comment and ignored during compilation. These comments are useful for writing longer explanations or temporarily disabling blocks of code.

Example:

package main

import "fmt"

func main() {

  /* This program prints "Hello World!" 

     to the screen. It's a simple demonstration. */

  fmt.Println("Hello World!")

}

Using Comments to Disable Code Execution

• Comments can be used to temporarily disable parts of your code, preventing them from being executed.

• This is helpful for testing, debugging, or saving code snippets for future reference and troubleshooting.

Example:

package main

import "fmt"

func main() {

    // Print a message to the screen

    fmt.Println("Hello World!")

    // The following line is commented out and will not be executed

    // fmt.Println("This line does not execute")

}
