Using the program below, identify the values of pid at lines A and C, and the values of pid1 at lines B and D. (Assume that the actual pids of the parent and child are 2600 and 2603, respectively.)

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*/
