Write a C program that generates the below process tree. Process P1 asks the user to enter two integers n1 and n2 (assume that the user always enters the value of n1 less than the value of n2). Then, after reading the values of n1 and n2 entered by the user and storing them in variables, process P1 creates three child processes P2, P3, and P4. Process P2 displays “Process P2: ”, and displays its ID and the ID of process P1. Process P3 displays “Process P3: ”, and displays your name, your ID, and your major. Process P4 displays “Process P4: ”, and displays the result of the multiplication of all even numbers between 3 and n2 (including n2 if it is even).
