Reading standard input

Every process owns its standard input, output, and error file descriptor. The stdin serves as the input of the process. This recipe describes how to read the data from the stdin.

How to do it...

1. Open the console and create the folder chapter05/recipe01.
2. Navigate to the directory.
3. Create the fmt.go file with the following content:

        package main

        import (
          "fmt"
        )

        func main() {

          var name string
          fmt.Println("What is your name?")
          fmt.Scanf("%s\n", &name)

          var age int
          fmt.Println("What is your age?")
          fmt.Scanf("%d\n", &age)

          fmt.Printf("Hello %s, your age is %d\n", name, age)

       }

4. Execute the code with go run fmt.go.
5. Enter the input John and press Enter.
6. Enter the input 40 and press Enter.

7. You will see the following output:

8. Create the file scanner.go with the following content:

        package main

        import (
          "bufio"
          "fmt"
        ...
