Write a C program grand_child.c where a parent creates a child process, the child creates its own child technically a grandchild of the original parent. The grandchild should be able to destroy its own code and turn into a Mozilla Firefox process (i.e. open a Firefox browser). The program should not have to close the Firefox browser window. You can manually close it. You can use code from the examples (fork.c etc.) from Canvas. But care should be taken that all essential requirements are met
