Assembly 列MASM中的数组输出
我正在运行一个程序,要求用户输入要显示的复合数字的数量。例如,如果用户输入10,程序将显示前10个复合数字 我遇到的问题是,我的程序在一个长列中打印所有值,我需要让输出以每行10个复合数字显示,每行之间至少有3个空格。代码如下:Assembly 列MASM中的数组输出,assembly,masm,irvine32,Assembly,Masm,Irvine32,我正在运行一个程序,要求用户输入要显示的复合数字的数量。例如,如果用户输入10,程序将显示前10个复合数字 我遇到的问题是,我的程序在一个长列中打印所有值,我需要让输出以每行10个复合数字显示,每行之间至少有3个空格。代码如下: INCLUDE Irvine32.inc .data userInt1 DWORD ? ;integer to be entered by user userInt2 DWORD ? ;integer t

关于如何在每行之间用3个空格打印10个元素,有什么建议吗
我实现了以下代码:
showComposites :
mov ecx, userInt1
jecxz farewell
mov edx, 10
isComposite:
mov eax, [ebx]
call WriteDec
dec edx
jnz Spaces
linebreak:
call crlf
mov edx, 10
jmp Next
Spaces:
cmp ecx, 1
je linebreak
mov edx, OFFSET space3
call WriteString
Next:
add ebx, 4
loop isComposite
输出直到第17个元素(而不是第10个元素)才换行
我一定错过了什么,因为换行符在10个元素之后没有发生
更新:修复了这个问题。我将计数器寄存器从edx更改为esi,它工作正常。您可以
半伪码:
Divide UserInt1 by 10
If Quotient > 0 OuterLoopCount=Quotient
OutterLoop:
Save OuterLoopCount
Initialize InnnerLoopCount=10
InnerLoop:
WriteDec & 3 Spaces
Add Array, TYPE
Loop InnerLoop
CRLF
Restore OuterLoopCount
Loop OuterLoop
Else Here
Move Remainder = Loop Count
ZeroQuotient:
WriteDec & 3 Spaces
Add array, TYPE
Loop ZeroQuotient
CRLF
...
你似乎对这个比较的结果一无所知
要解决您遇到的问题,您可以引入一个计数器,并使用值10进行初始化。每次输出CRLF时,将计数器重置为10
