How can you build a Go program for a different operating system or architecture using the go build command?

Use the -o flag followed by the desired OS and architecture.
Use the -os and -arch flags with the appropriate values.
Specify the target OS and architecture in the source code.
Use the -build flag followed by the target OS and architecture.

You can build a Go program for a different operating system or architecture using the go build command by using the -o flag followed by the desired OS and architecture. For example, to build for Linux on an AMD64 architecture, you would use go build -o myprogram-linux-amd64. The -o flag allows you to specify the output binary's name and location with the target OS and architecture in the filename.
