In your Lab assignment, you should have parsed the input expression from the keyboard, echoed it to the screen and called a subroutine with the input. In this MP you will write code to use a stack to
evaluate the expression. If the read value is an operand, push it onto the stack. If the read value is an operator, pop two values from the stack, apply the operator on the two values and push the result
back on the stack. Keep repeating this for every value read from keyboard and stop when you reach the ASCII value of the "=" (equal sign) character. If the last value is an operand, that means
the expression was invalid. If there is a stack underflow during any point in this process, then the expression was invalid. Do not worry about stack overflows. Look at the flowchart below for a detailed
description of the algorithm.
MP2 is due on Thursday, Sept. 21, by 10pm in your svn repository.

For example if the input the user entered on the keyboard was "3 4 -=", then the stack through the evaluation of the expression will be-
Start Read "3"(push x0003) Read "4"(push x0004) Read "-"(pop, calculate and push)
x0000 x0000 x0000 x0000
x0000 x0000 x0004 x0000
x0000 x0003 x0003 x
Examples:
Input Solution in decimal (stored in R5 as binary) Hexadecimal Output on screen
4 5 + 3 * 7 -= 20 (0000000000010100) x0014
5 2 8 * + 3 -= 18 (0000000000010010) x0012
5 1 2 + 4 * + 3 -= 14 (0000000000001110) x000E

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.
