Change shellcode. c as follows. what offset from the address of variable ret should be used here? in your report, explain how you use the assembly code to find out the layout of the variables in the program stack. assembly code can be obtained by using gdb disas command or gcc –s flag. also draw the program stack to analyze why the offset works. show the value of $esp and $ebp and the return address of main. compare the contents of the return address of main when entering and exiting main. print the address of variable shellcode and compare it with the contents of the return address of main.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
