Answer 1

package main

import (
    "fmt"
    "os"
    "runtime"
)

func main() {
    // Get the OS name (e.g., "windows", "linux", "darwin")
    osName := runtime.GOOS

    // Get the architecture (e.g., "amd64", "arm64")
    arch := runtime.GOARCH

    fmt.Printf("Operating System: %s\n", osName)
    fmt.Printf("Architecture: %s\n", arch)

    // Optionally, print the hostname (if needed for additional context)
    host, err := os.Hostname()
    if err == nil {
        fmt.Printf("Hostname: %s\n", host)
    } else {
        fmt.Println("Error fetching hostname:", err)
    }
}
