Question 1 Write a C program which takes four command line arguments: two file names and two number of elements. Your program must check if correct number of arguments are supplied and terminate if not. Your main process must create three processes: The first and second processes must open / create files by the given names and fill them with the given number of random integers (one integer per line) and terminate. The third process must execute "sort" command with necessary arguments so that it numerically sorts both files and display the combined result on screen. Before creating the third child process, main process must wait for the other two child processes to end. Sample Run $ ./question1 randfile1.txt randfile2.txt 40 70 [PARENT] Creating first process... [PARENT] Creating second process... [CHILD1] Writing 40 random integers to randfile1.txt... (78 32 56...) [CHILD2] Writing 70 random integers to randfile2.txt... (46 In 88 45...) [PARENT] Creating third process... [CHILD3] Sorting both files: 32 45 46 in 56 In 78 88 ... [PARENT] Done
