Linux Linux program Exercise 14 (Multi-process stress test)

/** Title: * Programming a basic multi-process test framework, prompting the user to enter the number of processes, and the number of running laps per process. (fork) * For multi-process stress testing. (EXECVE) * requires the parent process to monitor the exit of all child processes and avoid the zombie process.
