A)From the program above, identify the values of pid at lines A, B, C, and D. (Assume that the actual pids of the parent and child are 2600 and 2603, respectively. Also assume that fork will always succeed.)

B) List all of the possible outputs (just write the A/B/C/D text; no need for pids) that could be generated by the program.

int main() ( pid t pid, pid1; /* fork a child process */ pid = fork(); if (pid 0) { /* error occurred */ terinttstdec, "Fork Failed"); return 1; else if (pid == 0) { /* child process printf('' child: Rad = %d", Rid); printf( "child: pidl %d", = pid1); /* B*/ else /*parent process/ pid! = geteid(); printf("parent : Rid-%d", pid); printf("parent : pid! =%d", wait(NULL); pid1); /* D*/
