A way is to do directly with shell command:

system("ping 10.50.132.10 -t >> file.txt");

After your operations, you can read from "file.txt"!

There are a couple solutions to this. The first and simplest would be to simple add a redirect in the system call:

system("ping 10.50.132.10 -t > some_file.txt");

Another and more advanced way would be to read the output into your program, and write it out to file yourself. For this look either at _popen or CreateProcess.
