Step by Step solution about How to resolve the algorithm Check output device is a terminal step by step in the Go programming language

This Go program checks whether the standard output is a character device or not. A character device is a type of file that represents a device that can be accessed character by character, such as a terminal window. The program first gets the file info for the standard output using the Stat method. It then checks if the mode of the file info has the os.ModeCharDevice bit set. If it does, it means that the standard output is a character device, and the program prints "Hello terminal". Otherwise, it prints "Who are you? You're not a terminal".

Here is how the program works step by step:

1. The program imports the os and fmt packages.
2. The main function is the entry point of the program.
3. The main function gets the file info for the standard output using the Stat method.
4. The main function checks if the mode of the file info has the os.ModeCharDevice bit set.
5. If the mode has the os.ModeCharDevice bit set, the main function prints "Hello terminal".
6. Otherwise, the main function prints "Who are you? You're not a terminal".

package main

import (
    "os"
    "fmt"
)

func main() {
    if fileInfo, _ := os.Stdout.Stat(); (fileInfo.Mode() & os.ModeCharDevice) != 0 {
        fmt.Println("Hello terminal")
    } else {
        fmt.Println("Who are you? You're not a terminal")
    }
}
