(b) Write a NEAR subroutine using 8086 assembly Language (with proper comments) that returns the average value of the values stored in a byte array of length 3. All three values of the byte array are passed to the subroutine in the stack. You should write both the calling program and subroutine.

Certainly, below is an example of a calling program and a NEAR subroutine written in 8086 assembly language that calculates the average value of a byte array of length 3. The values of the byte array are passed to the subroutine through the stack.

**Calling Program:**


section .data

    array_values db 10, 20, 30

section .text

    global _start


    ; Load array values onto the stack

    mov al, [array_values]

    push ax

    mov al, [array_values + 1]

    push ax

    mov al, [array_values + 2]

    push ax

    ; Call the subroutine

    call calculate_average

    ; Display the result

    mov ah, 4Ch

    int 21h


    ; NEAR subroutine to calculate average

    pop bx  ; Pop the first value

    pop ax  ; Pop the second value

    add ax, bx  ; Sum of the first two values

    pop bx  ; Pop the third value

    add ax, bx  ; Sum of all three values

    mov bx, 3  ; Number of elements

    div bx  ; Divide the sum by the number of elements

    ; AX now contains the average value

    ; Display the result (for demonstration purposes)

    mov ah, 2

    int 21h



This program defines an array with three values (10, 20, 30) and calls the `calculate_average` subroutine to calculate and display the average value.

Note: The subroutine `calculate_average` assumes that the array values are integers, and the average is an integer. If you want to handle floating-point averages, you would need to adjust the subroutine accordingly.
