Assuming that the actual process ids of the parent and child processes are 5000 and 5004 respectively, what will be printed out at lines A, B, C, D, E, and F? Be sure to explain your answers. int main() { pid_t pid, pid1; int value = 1500; /* fork a child process */ pid = fork(); if (pid < 0) { /* error occurred */ fprintf(stderr,Fork failed); return(1); } else if (pid == 0) { /* child process */ pid1 = getpid(); printf(child: pid = %d,pid); /* A */ printf(child: pid1 = %d,pid1); /* B */ value += 100; printf(child: value = %d,value); /* C */ } else { /* parent process */ wait(NULL); pid1= getpid(); printf(parent: pid = %d,pid); /* D */ printf(parent: pid1 = %d,pid1); /* E */ value += 300; printf(parent: value = %d,value); /* F */ } return(0); }
