Question 1 Write a C program which takes two arguments from command line: one filename and one number of items. Your program must check if correct number of arguments are supplied and terminate if not. Your program must create three child processes in the following order: first child process creates the mentioned file and fills it with the specified number of random characters (a-z). The second child process executes "zip command to make a compressed copy of your file. The third child process must execute "Is" command to display both files. Between each child process, parent must wait for termination of former process to create the new process. Sample Run $ ./question1 chars 40000 [PARENT] Creating first process... [CHILD1] Writing 40000 random chars to chars.txt... [PARENT] Creating second process... [CHILD2] Executing zip command... adding: chars.txt (deflated 37%) [PARENT] Creating third process... [CHILD3] Executing ls command... 40000 chars.txt 25492 chars.zip [PARENT] Done
