ip address octet increments
Hi all,
Situation is as below.
I would get an IP address and port from eithe r a file or command line. It probably would be as char * or string. So was wondering how I could accept this and increment the last octets?
Incrementing the port is fine. I could get that into an integer by atoi() and then increment it.
But the IP address part is getting tricky. Any say please?
