Define a function updatetimewindow() with parameters timestart, timeend, and offsetamount. each parameter is of type int. the function adds offsetamount to each of the first two parameters. make the first two parameters pass by pointer. sample output for the given program: timestart = 3, timeend = 7 timestart = 5, timeend = 9

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
