خيلي ممنون ولي اين اسمبلي نيست كه؟
کاربرد زبان اسمبلی در زبان c و شباهت توابع!نقل قول:
---------- Post added at 01:45 PM ---------- Previous post was at 01:42 PM ----------
این یکی به زبان اسمبلی :
print macro msg
mov dx,offset msg
mov ah,09h
int 21h
endm
data segment
msg1 db "Enter the number:$"
msg2 db 10,13,"Factorial is:$"
data ends
code segment
assume cs:code,ds:data
start:mov ax,data
mov ds,ax
print msg1
mov ah,01h
int 21h
sub al,48
mov dl,al
mov ax,1
l:mul dl
dec dl
cmp dl,0
JNZ l
add ax,48
mov dx,ax
mov ah,02h
int 21h
mov ah,4ch
int 21h
code ends
end start
با تشکر
