OS-(I) Assignment 1: Operations on Processes

Set A.

(1) Implement the C Program to create a child process using fork(), display parent and child process id. Child process will display the message “I am Child Process” and the parent process should display “I am Parent Process”.

 

(2) Write a program that demonstrates the use of nice() system call. After a child process is started using fork(), assign higher priority to the child using nice() system call.

Set B.

(1) Implement the C program to accept n integers to be sorted. Main function creates child process using fork system call. Parent process sorts the integers using bubble sort and waits for child process using wait system call. Child process sorts the integers using insertion sort.

 

(2) Write a C program to illustrate the concept of orphan process. Parent process creates a child and terminates before child has finished its task. So child process becomes orphan process. (Use fork(), sleep(), getpid(), getppid()).
