Problem Statement

For this exercise a program is open a socket to localhost on port 256 and send the message "hello socket world" before closing the socket. Catching any exceptions or errors is not required.

Let's start with the solution:

BEGIN { 
    s="/inet/tcp/256/0/0"
    print strftime() |& s
    close(s)
}


BEGIN {
    s="/inet/tcp/0/localhost/256"
    s |& getline
    print $0
    close(s)
}
