[Addressing Modes] Copy the following code into your assembly development environment and single-step through it. For those instructions referencing memory, write the linear address.
TITLE Addressing Modes (main.asm)
INCLUDE Irvine32.inc
.data
alpha DWORD 44h, 23h
beta DWORD 6788h, 66h
gamma DWORD 1234h
.code
main PROC
mov eax, 12h; Immediate
mov ecx, eax; Register to Register
mov edi, OFFSET beta; Immediate
mov [gamma], eax; Indirect
mov esi, [gamma]; Direct
mov esi, 4; Immediate

END main
[Indirect addressing] Write a program that adds a constant value to each element of an array and places the value in the ModArray. Use:
.data
Array WORD 23h, 45h, 45h, 56h, 25h, 44h, 22h, 54h, 12h
ConstVal WORD 20h
ModArray WORD 9 DUP (?)
[Loops] Write a program to compute the sum of first n even integers. Sum = 2 + 4 + 6 … + n. Your program must:
Prompt user for integer n,
Read the value of n from user input
Calculate Sum, and;
Print Sum on screen.
Please use the “WriteInt” procedure, not “DumpRegs”. Other relevant procedures: “ReadInt” and “WriteString.” The calculation can be done in many ways, and all submissions that evidence proper programming practice are acceptable. In your homework submission, please embed both the code and one screen shot for n = 60. You can assume that the user is considerate and careful and thus only inputs even values for n.
