(e) Assume that two processes named client and server running in the system. It is required that these two processes should communicate with each other using shared memory concept. The server writes alphabets from a..z to the shared memory.the client should read the alphabets from the shared memory and convert it to A...Z. Write a program to demonstrate the above mentioned scenario. (Medium) (c) Process and Thread Management Write a program to create a thread and perform the following (Easy) Create a thread runner function Set the thread attributes Join the parent and thread Wait for the thread to complete . . (b) Parent child process creation using fork() and exec() system call Checking the Process Identifier Assigning new task to child Providing the path name and program name to exec() Synchronizing Parent and child process using wait()
