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*/

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
