pls give answers for this
The Fibonacci sequence is the series of numbers 0, 1, 1, 2, 3, 5, 8, .... Formally, it can be expressed as: f ib0 = 0 f ib1 = 1 f ibn = f ibn−1 + f ibn−2 i. Write a C program using the fork() system call that that generates the Fibonacci sequence by the child process. ii. If the user input as 5 then the child process has to output up to the 5 that is output must be 0,1,1,2,3,5. iii. Parent has to print the child process id and child has to print the parent process id. iv. Parent has to finish only after the child terminates. v. Is there any process synchronization problem here? Justify your answer. vi. Modify the above program to create a zombie process. How do y ou identify the zombie process? vii. Modify the above program to create an orphan process. viii. Compare and contrast the process and threads.

1. Solve synchronization problems inherent in inter-process communication and multi-threaded applications.
1. Process control system calls: The demonstration of fork, execve and wait system calls along with zombie and orphan states.a. Implement the C program in which main program accepts the integers to besorted. Main program uses the fork system call to create a new process called a child process. Parent process sorts the integers using merge sort and waits for child process using wait system call to sort the integers using quick sort. Also demonstrate zombie and orphan states.b. Implement...

The goal of this assignment is to write a multithreaded program (Task3.c) that explores synchronization challenge 1. Assume that we have a shared variable CurrentiD. This is initialized to 1 at the beginning. 2. Now create 5 threads in your program and assign ID 1,2,3,4,5 to them respectively. You can pass the ID as a parameter when you create the threads. Each of the threads will try to access the variable "CurrentiD" Whenever a thread acquires the variable, it checks...

I will provide, best rating. Please help me out understand how to solve part 2 of this problem. I'm not sure how to make this work using ONLY the exec-family. No system() function call. 1. Using either a UNIX or a Linux system, write a C program that forks a child process that ultimately becomes a zombie process. This zombie process must remain in the system for at least 10 seconds. Process states can be obtained from the command: ps...

Complete the following C code by filling all “???”sto write a C program to create a child process. Before the child process is created, an integer variable A is defined and assigned value 10. Then in the child process, A is reduced by 5. After the child process completes, the parent process increases A by 5. Then what will A’s value be just before the parent process completes? Why? Write the code and run it to verify your answer. #include...
