Write an assembly code to calculate and print the result of an expression entered by user. Here are the details of your code: 1- You should use the emulator emu8086. 2- Your code should ask the user to input an arithmetic expression, then the code will print the result on the screen. 3- Your code allow the following operations ONLY: Addition (+) Subtraction (-) Multiplication (*) Division (/) Mod (%) Factorial (!) 4- Your code should contains 6 procedures (one procedure per operation). Here are the procedures that should be included in your code: Addition: This function add two integer numbers. Subtraction: This function subtract two integer numbers. Multiplication: This function multiply two integer numbers. Division: This function divide two integer numbers. Mod: This function calculate the reminder of division operation between two integer numbers. Factorial: This function calculate the factorial of a positive integer number. For example: 4! = 4*3*2*1= 24 5! = 5*4*3*2*1 = 120 5- Assume the range of numbers that entered by the user is (-127 - +127) 6- PAY ATTENTION: NOT allowed to use MUL, IMUL, DIV or IDIV instructions in your code. 7- If the user enter any operation or character other than the allowed operation, your code should print Error: The operation is not valid. 8- This assignment will be done in groups; two students for each group. 9- The deadline for this assignment will be on Wednesday (6-1-2021) at 11:59 PM. You should submit your code on the eLearning before the deadline.
