Write a C/C++ program called signal-parent.cpp that waits a brief period of time (10 seconds; using the sleep function) to simulate a daemon process initializing and then waiting for an incoming request.

After this period, the parent process should fork/exec (don't use the system() function call) a child process (call it signal-child.cpp). The parent process should then sleep for a longer period of time (2 minutes).

The parent process should determine when the child process exits. The parent process should report the child's PID and it's return/exit status.

The child process should also sleep for a period of time (30 seconds) to simulate a child process performing some work on behalf of the user. After the child process wakes up, it should simply exit with a value of 53.

At each step, both processes should output an informational message to help us understand what is happening, such as the following: parent: forking child child: going to sleep etc. (This information would typically be written to a log file; you may simply write to stdout.)
