我想解決我得到的練習。任務是從終端讀取10個整數並以相反的順序打印出來。要做到這一點,應該使用堆棧。我已經試過這樣:組裝堆棧 - 反向輸入並打印出
%include "asm_io.inc"
segment .data
prompt db "Please enter a number: ", 0
segment .text
global asm_main
asm_main:
enter 0,0
pusha
mov ecx, 10 ; for loop counter
for_loop:
mov eax, prompt
call print_string ; print prompt
call read_int ; read input
push dword eax ; push input to stack
loop for_loop
mov ecx, 10 ; set loop counter for output
swap_loop:
pop eax ; get last input from stack
call print_int
call print_nl
add esp, 4 ; increment esp for next value to take from stack
loop swap_loop
popa
mov eax, 0
leave
ret
當我執行該程序,並從1到10輸入所有數字依次我得到以下結果:
Should Be:
10 10
8 9
6 8
4 7
2 6
-1217249280 5
-1079315368 4
0 3
-1079315312 2
