Implement the following C++ expression in assembly language, using 32-bit unsigned operands:

ask the user to enter val2, val1, val3 by calling Readint

If (val2 ==0) then

{val2 = 1}

val1 = (val3 / val2) * (val1 + val3)

Val1 = 600

Val2 = 0

Val3 = 1000

Write an assembly language program that moves the number 2 to BL and 0 to AL. Add BL to AL ECX many times having AL as the destination. Move 10 into ECX before the loop. What will the value of AL when the loop is done?

Write an assembly language program that declares three integer variables called number1 initialized to 9, number2 initialized to 15 and number3 initialized to 23. The assembly language code must add the three numbers and move the result into ebx. The program also must find the difference between number2 and number3 (i.e. 15 – 23). The difference must be placed in edx.
