When you type "/lib/cpp" of course it's going to just sit there. It's waiting for something to do. Try a more finite command like "/lib/cpp --version".
BTW, ctrl-Z does not kill the running program. It just moves it to the background. It's still running there in the background, still waiting on something to do. Type "fg" to bring the process back to the foreground. Then use ctrl-C to kill it.
