以下是用汇编语言编程求1*2*3*4*5*6*7,将结果存入fac中并显示出来的代码:
```assembly
section .data
fac dd 1
section .text
global _start
_start:
mov ecx, 1
mov eax, 1
loop:
cmp ecx, 7
jg end_loop
inc ecx
imul eax, ecx
jmp loop
end_loop:
mov [fac], eax
; 显示结果
mov eax, 4
mov ebx, 1
mov ecx, fac
mov edx, 4
int 0x80
; 退出程序
mov eax, 1
xor ebx, ebx
int 0x80
```
