Question

Write a 80 86 code fragment that accesses each element of an array (anArray) and stores the array elements which are below average in another array (bArray).

1. Assume the following data section.
anArray DWORD 100 DUP(?) ; maximum size of a number array
count DWORD ? ; actual number of array elements
avg DWORD ? ; average of array elements
bArray DWORD 1000 DUP (?) ; maximum size of a number array

2. Assume that the actual number of array elements is stored in count.
3. You do not need to compute the average. Assume that the average of the array is stored in avg.

Explanation / Answer

Dear, .model small .stack 100h .data   ; intialize data segment anArray DWORD 100 DUP(?) count     DWORD ? avg        DWORD ? bArray   DWORD 1000 DUP(?) .code    main proc    mov ax, @anArray ; array initialization    mov ds, ax    mov bx, @bArray    ; below array average initialization    mov si, offset anArray    mov di, offset bArray    mov cx, count         ; count the number of array l1: mov al,[si]    inc cx                     inc si    add dx, ax               ; sum the array elements    cmp cx, 0                ; check the count    jae    l1    mov cx, count         ; initialize count    div dx, cx                ; calculate average    mov al, [si]              ; initialize array    inc cx                      ; increment the count    inc si                       ; increment source index to compare    cmp dx, ax               ; compare with average    jb l2                         ; if its less than average    exit               l2: mov [di], al             ; store in another array     inc di        exit
