A UDP client

If you know how to develop a TCP client, then you should find developing a UDP client much easier due to the simplicity of the UDP protocol.

The biggest difference between UDP and TCP is that UDP is not reliable by design. This also means that, in general, UDP is simpler than TCP because UDP does not need to keep the state of a UDP connection. Put simply, UDP is like "fire and forget," which in some cases is perfect.

The name of the utility presented for this topic is UDPclient.go, and it will be presented in four code segments. The first part of UDPclient.go is as follows:

package main 
 
import ( 
    "bufio" 
    "fmt" 
    "net" 
    "os" 
    "strings" 
) 

The second segment of UDPclient.go is as follows:

func main() { arguments := os.Args if len(arguments) ...
