答：大致看了下，这个不只是1不1的问题了。。算法太过理想化。 既然你的数是用户输入的，那么几位数是事先未知的，你怎能对齐的算？而且是以0d回车结尾的。你所谓的对齐是不对齐的，你要正确的结果只能是让用户这么输入00012+00013。那你的程序就没意义了。其实你完全可以把输入的字符串转换成数字，...

你的这个程序是不是错了？应该有个edi的地址吧？怎么两个都是esi呢？mov cx,20
lea si,buffer1
lea di,buffer2
rep movsw 的程序，是把buffer1里的数据安字传送到buffer2里，传20个次（如果20是10进制的话，）
rep先执行
rep第一次执行时判断cx是否为0，为0执行下面的指令，不为0时，cx减一，并执行后面的movsw指令，movsw就是传送数据。

答：大致看了下，这个不只是1不1的问题了。。算法太过理想化。 既然你的数是用户输入的，那么几位数是事先未知的，你怎能对齐的算？而且是以0d回车结尾的。你所谓的对齐是不对齐的，你要正确的结果只能是让用户这么输入00012+00013。那你的程序就没意义了。其实你完全可以把输入的字符串转换成数字，...
