微機接口課程設(shè)計

2、如相同,則顯示”match”,否則，顯示“no match”.4、將鍵盤輸入的小寫字母轉(zhuǎn)換成大寫字母的設(shè)計 接收鍵盤字符（-c為結(jié)束），并將其中的小寫字母轉(zhuǎn)換為大寫字母，然后顯示在屏幕上5、計算n！設(shè)計編寫計算n！的程序。數(shù)值n由鍵盤輸入，將結(jié)果在屏幕上輸出。n的范圍為0-65535.即剛好能被一個16位寄存器容納。1、從鍵盤輸入數(shù)據(jù)并顯示設(shè)計流程圖入口段寄存器和堆棧初始化顯示“請輸入十六進制數(shù)”調(diào)用getnum接收鍵入數(shù)值，保存在bx中計數(shù)值16送cxb x中內(nèi)容循環(huán)左移1位bl送dl，屏蔽掉dl高7位dl加30h，變成二進制數(shù)位對應(yīng)字符的ascii顯示cx減1為0？ n返回dos程序crl
