已知一个矩阵,存放在字节数据区BUF中,编写程序计算矩阵每一行元素之和.

[langwo1334]

BUF db 11h,12h,13h,14h,15h
db 21h,22h,23h,24h,25h
db 31h,32h,33h,34h,35h
db 41h,42h,43h,44h,45h
用两重循环.本人刚刚学习,请教各位了.

我的汇编快忘光了

要32位的说一声哦

麻烦了,调试的时候还是有问题,debug不出来东西,加了个输出是死循环...

[killbug2004]

debug b.exe
-g bdb:3e
-r
-d ds:10 ======>看数组

-d ds:14 ======>看结果,注意是word,高位在前面

ps:你可以输出到控制台,不过我不想去查中断表,上面的偏移是开始u命令看的
