Sub Task 2: Create another console application, "parent". It create a child process to execute “child”. The "parent" process keeps printing out "The parent is talking at [system time]". (one per 1s) Execute "pare nt" and explain the output you see. Sub Task 3: Create a "winPS" program which can output information about all the running processes.

Both the main thread and the child thread keep printing out "[ThreadID] + [System time]". session2 Objective： Create "ps" and "kill" commands on Windows. Requirement： Sub Task 1: On Linux/Unix there are a "ps" command and a "kill" command. The "ps" command can list information about all the running processes. The "kill" command can terminate processes. Based on the tasks finished in Session 1, create "ps" and "kill" commands on Windows.
