Added the following flags : -c to make a NUMBER of pings -f to add flood mode -i to set an interval of NUMBER seconds between pings -l to send a NUMBER of pings as fast as possible then swapping to normal mode -q to add quiet mode Refactored main.c : Made flags.c for avoiding the main() function becoming a masterclass and make the file more readable Moved some function from main.c to utils.c Made some change to mimic the behavior of the ping binary of inetutils2.0
