Consider the following program: #include #include int main (int argc, char** argv) { printf("F\n"); fork () ; printf ("C\n"); if (fork ()) ( printf ("E\n"); fork (); printf ("F\n"); } else ( printf ("B\n"); } fork (); printf ("A\n"); return 0; How many processes are created by the execution of this program (including the initial process)? If standard output buffers are never flushed until a process exits, how many times will the letter E be output? If standard output buffers are always flushed when a newline is output, how many times will the letter E be output? What is the smallest number of lines of text that this program will output when run (assuming that all fork() calls succeed)?
