Question

Write a program in Assembly language that calculates the maximum and minimum of 10 numbers stored in memory and writes them to the memory locations.

#using loop

num: dw 56, 45, 36, 67, 76, 22, 89, 12, 29, 83

min: dw 0

max: dw 0

I wrote a codem but I got an error when I executed it

[ORG 0x0100]

jmp start

num: dw 56, 45, 36, 67, 76, 22, 89, 12, 29, 83
min: dw 0
max: dw 0

start: mov ax, [num]
mov bx, 0
mov cx, 10
move [max], ax
mov [min], ax

again:
mov ax, [num+bx]
add bx, 2
cmp ax, [max]
Jl next
mov [max], ax
next: mov [min], ax
loop again

end: mov ax, 0x4c00 ;terminate program
int 0x21

Program[ executed and verified in emu8086 simulator]

Note:- memory values are represented in hexa decimal format

DATA SEGMENT

num dw 56, 45, 36, 67, 76, 22, 89, 12, 29, 83
min dw ?
max dw ?
DATA ends

CODE SEGMENT
ASSUME cs:code, ds:data
start: mov ax, data
