Is it possible to ping another computer using c++ and save the results in a text file or something?
Typing “ping.cpp” into http://www.google.com resulted in many links, including this one, which has source code for ping. The text file output feature is left as an exercise for the reader

As Arjuna34 pointed out, sure it’s possible in c++, but is there any particular reason you want to do in in c++? It would be significantly easier to do it a language like perl. What OS are you using anyway? Is this part of a larger project, or do you just want to keep track of a Quake server somewhere? If your using unix or a varient, it can be done in one line of code. Let us know a bit more about what you’re trying to accomplish, and perhaps we can be of more help.
