Write a program using the fork() system call to do thefollowing. The parent process (main program) forks a process(CHILD 1) to compute and print the sum of first n integers where n is a variable shared between the parent and CHILD 1. Have the parent invoke the wait () call to wait for both the child processesto complete before exiting the program. IN A C program

Write a program in C using the fork() system call to do the following. The parent process (main program) forks a process (CHILD 1) to compute and print the sum of first n integers where n is a variable shared between the parent and CHILD 1. It also forks another process (CHILD 2) that finds the sum of squares of the first n numbers where n is a variable it shares with the parent. Let CHILD 1 print “The sum...

Part 2. System Programming and Process Management You are asked to develop basic system programming including process creation and termination on a Linux platform in this part of programming project. You are asked to create multiple children processes to work under one parent process. In theory, children processes can do their own work separately or cooperatively to accomplish a task. In this assignment, these children processes simply print out a "hello"...

Write a “C” program that creates a child process that prints out its pid and new line and then calls pause() system call. Once it returns from the pause system call the child program must exit with code 5. The parent program must wait for the child process and print out the pid of the child process and the exit status with the following format: “childpid=%d,exitstatus=%d\n”.

C program To develop a C program to implement a process system call. PROBLEM You are to use the Ubuntu operating system to write a C program that creates a process to determine the identification of the current user of your computer. I mean if joe is the login of the current user of your computer your solution should return joe. Your solution must also provide the pid of both the parent and the child processes. You may use the...

Please I need help with this problem Write a c++ program that will accept the names of 3 processes as command-line arguments. Each of these processes will run for as many seconds as (PID%10)*3+5 and terminate. After those 3 children terminated, the parent process will reschedule each child. When all children have been rescheduled 3 times, the parent will terminate. Each child must print out its process id every time it runs.

Assignment: Using the Fork System Call The Collatz conjecture concerns what happens when we take any positive integer n and apply the following algorthm: n={n / 2 , if n is even 3 * n + 1 , if n is odd The conjecture states that when this algorithm is continually applied, all positive integers will eventually reach 1. For example, if n = 35, the sequence is: 35, 106, 53, 160, 80, 40, 20, 10, 5, 16, 8, 4, 2,...
