I am having trouble of getting the coding working because I have four errors and I have hard getting the sum and odd even working I have got the odd number sun working. But now it won’t bring out my even number sum and keeps asking for a number.
My loop asks for the number, I then mov eax to the ebx and clear for division. If it is even I jump it out of loop and do addition for the even sum in that exit loop. I loop back to L1 from there and have it finish adding the odd numbers which will come out properly. After that it just endlessly asks me to enter a number.
instruction:
Lab 7A - Summing Numbers
Ask the user for the amount of numbers they would like to input. Construct a counted loop that will run the number of times the user specified. Inside the loop input numbers from the keyboard and sum all of the odd and even numbers. Use two DWORD variables to hold the odd and even sums. Create a DWORD variable called divisor and store 2 in it. This will be used to divide the number input.
Do not use .IF and .ELSE constructs
Your program should look like the following:
How many number do you want to input?
5
Enter a number
1
Enter a number
2
Enter a number
3
Enter a number
4
Enter a number
5
The sum of the even numbers is 6
The sum of the odd numbers is 9

Something to consider:
When you read a number from the keyboard. You need to store it to another register before calling the div instruction. Remember, the div instruction will modify both the eax and the edx register. If you store the value read into the ebx for instance you can simply add it to the even or odd sum depending on the result of the division.
my code
INCLUDE asmlib. inc
.data
sum DWORD 0
evenCount DWORD 0
oddCount DWORD 0
divisor DWORD 2
msg BYTE "How many numbers do you want to input?",0
prompt BYTE "Enter a number ", 0
outpEven BYTE "The sum offset the even numbers is ", 0
outpOdd BYTE "The sum of the odd numbers is",0
.code
main PROC
mov edx, OFFSET msg ;prime the loop
call writeLine ;getting the first
call readInt ;number
mov ecx, eax
mov edx, OFFSET prompt
L1:
call writeLine
call readInt
mov edx, eax ;store eax
mov edx, 0 ;clear for the division
div divisor ;divide by 2
cmp edx, 0
jne EVEN
inc evenCount
add sum, eax
mov edx, OFFSET prompt
call writeString
call writeInt
LOOP L1

inc evenCount,0
