Printing output

The simplest way to print something in Go is using the fmt.Println() and fmt.Printf() functions. The fmt.Printf() function has many similarities with the C printf(3) function. You can also use the fmt.Print() function instead of fmt.Println().

The main difference between fmt.Print() and fmt.Println() is that the latter automatically prints a newline character each time you call it. The biggest difference between fmt.Println() and fmt.Printf() is that the latter requires a format specifier for everything it will print, just like the C printf(3) function. This means that you have better control over what you are doing, but you have to write more code. Go calls these specifiers verbs, and you can find out more about supported verbs at https://golang.org/pkg/fmt/.
