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 integers (0-1000), one number per line. The second child process executes "sort" command to sort the numbers in this file on screen. The third child process must find the minimum and maximum numbers in this file. Between each child process, parent must wait for termination of former process to create the new process. Sample Run $ ./question1 nums.txt 15 [PARENT] Creating first process... [CHILD1] Creating nums.txt with 15 integers... [PARENT] Creating second process... [CHILD2] Executing sort command... 56 133 147 [PARENT] Executing third process... [CHILD3] Min: 56, max: 839 [PARENT] Done.
