Study, compile and run the following programs. a. section 3.3 fork.c b. section 3.4 fork-exec.c c. section 4.1 thread-create.c d. section 4.2 thread-create2.c 3. Write a menu-driven c program that allows you to do the following under menu control. a. fork a process that will display your root directory. b. Input a file name and fork the emacs editor to create or modify the file. c. Input the name of a c program, and fork the gcc compiler to compile and link it. NOTE: Ensure that your code distinguishes the parent from the child process so that you don’t create a fork bomb. The parent should wait for the child to finish before proceeding in the menu loop.
