What are the benefits of using GOARCH and GOOS environment variables

1. Cross-Compilation: These variables allow you to cross-compile Go programs for different operating systems and architectures. This is particularly useful for building binaries that can run on multiple platforms.

2. Platform-Independent Code: By setting `GOOS` and `GOARCH`, you can ensure that your Go code is platform-independent and can run on different operating systems and architectures without modification.

3. Easy Build Process: Using `GOOS` and `GOARCH` simplifies the build process by allowing you to specify the target platform and architecture directly in the build command. This eliminates the need to manually configure the build environment for each platform.

4. Portability: The `GOOS` and `GOARCH` variables ensure that your Go code is portable across different platforms, making it easier to distribute and deploy your applications.

5. Flexibility: These variables provide flexibility in building Go binaries for various platforms and architectures, which is essential for developing applications that need to run on multiple environments.

Here are some examples of how to use `GOOS` and `GOARCH` in Go:

go
package main

import (
    "fmt"
)

func main() {
    fmt.Println("Operating System: ", os.Getenv("GOOS"))
    fmt.Println("Architecture: ", os.Getenv("GOARCH"))
}

In this example, `os.Getenv("GOOS")` and `os.Getenv("GOARCH")` are used to get the current operating system and architecture, respectively.
