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". Here are the examples of the expected output: Please Enter your expression: 10+5 The result of the 10+5 is 15 Please Enter your expression: 10-5 The result of the 10-5 is 5 Please Enter your expression: 10*5 The result of the 10*5 is 50 Please Enter your expression: 10/5 The result of the 10/5 is 2 Please Enter your expression: 10%5 The result of the 10%5 is 0 Please Enter your expression: 5! The result of the 5! is 120 Please Enter your expression: 10@5 Error: The operation is not valid
