2、DW?編制程序求出該 ARRAY數(shù)組中的最大數(shù)放入MAX單元。data segmentarraydw 12,78,55,4,125,96maxdw ?dataendscodesegmentassume cs:code,ds:datastart:movax,datamovds,axmovsi,0movax,arraysimovcx,5again:add si,2dec cxjcxzexitcmpax,arraysijaagain精品文檔movax,arraysijmp againexit:movmax,axmovah,02hint21hmovah,4chint21hcodeendsend sta

3、rt預(yù)留字符串口令 , 輸入口令串與預(yù)留密碼串比較。若匹配則顯示“ MATCH！CONGRATULATION”,否則顯示“ NOMATCH!”, 并讓用戶重新輸入，程序能對口令進(jìn)行測試，但測試次數(shù)最多3 次，若 3 次輸入密碼皆錯，給出相應(yīng)的提示信息，程序退出。data segmentpassworddb 123456inputdb20,?,20 dup(?)countequ 6str1db0dh,0ah,match!congratulation$str2db0dh,0ah,no match!please input again:$str3db0dh,0ah,please intout you
