Assembly Language Code Help

Part 1

Implement the following C++ code fragment in assembly language. Use the block-structured .IF and .WHILE directives. Assume that all variables are 32-bit integers.

      int array[] = {3,1,4,1,5,9,2,6, 5,3,5,8,9,7,9,3,2,3,8,4};
 int lower = 3;
 int upper = 8;
 int ArraySize = sizeof array / sizeof lower;
 int index = 0;
 int sum = 0;
 while( index < ArraySize )
 {
      if( array[index] >= lower && array[index] <= upper )
      {
          sum += array[index];
      }
      index++;
 }

Your assembly language program must also display as output the number of times a member of ' array 'e qualified for inclusion into the ' sum 'e and what the final value of the variable ' sum 'e was. (Hint: you may have to add another variable.) Feel free to use the author's procedures in the book's link library. Use only the procedures that were introduced in chapter 5.

Part 2

Write a program that asks the user to enter an integer dollar amount between 1 and 5,000. Your program should display the corresponding class description using the following table. Write the program so that it executes until the user inputs some value that you determine to be the "stop value". Your program must guard against and provide user messages for input values that are outside the valid range.

Donation Amount (dollars) Class of Donation $4,000 to $5,000 Platinum $3,000 to $3,999 Gold $2,000 to $2,999 Silver $1,000 to $1,999 Bronze $1 to $999 Copper

This is what I have so far:

INCLUDE Irvine32.inc

.data

sum DWORD 0

index DWORD 0

array DWORD 3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9, 3, 2, 3, 8, 4

lower DWORD 3

upper DWORD 8

ArraySize = ($ - Array) / TYPE array

message1 db "Enter an amount between $1 and $5000 (or enter 0 to quit): ", 0

message2 db "Class of Donation: ", 0

message3 db "Error:Donated amount must be between $1 and $5000!!", 0

.code main PROC

      .IF eax > 5000
      mov edx, OFFSET message3
      call WriteString
      jmp quit
      .ENDIF

      cmp  eax, 0
      je   quit

      .IF eax >= 4000
      mov al, "P"

      .ELSEIF eax >= 3000
      mov al, "G"
      .ELSEIF eax >= 2000
      mov al, "S"
      .ELSEIF eax >= 1000

      call WriteChar

Someone Please help me complete this.. I am completely new to Assembly Language and I've been trying this for couple of days already. I don't know what's wrong with this code :( Help!!
