【单选题】以下哪个程序片段可以实现 2018+1916,()
A. MOV AL,2018 ADD AL,1916 B. MOV AX,2018 MOV AX,1916 ADD AX,AX C. ADD 2018,1916 D. MOV AX,1916 ADD AX,2018
A. MOV AL,2018 ADD AL,1916 B. MOV AX,2018 MOV AX,1916 ADD AX,AX C. ADD 2018,1916 D. MOV AX,1916 ADD AX,2018
举一反三
- 写出每条汇编指令执行后相关寄存器的值 mov ax,62627 AX=________________ mov ah,31H AX=________________ mov al,23H AX=________________ add ax,ax AX=________________ mov bx,826CH BX=________________ mov cx,ax CX=________________ mov ax,bx AX=________________ add ax,bx AX=________________ mov al,bh AX=________________ mov ah,bl AX=________________ add ah,ah AX=________________ add al,6 AX=________________ add al,al AX=________________ mov ax,cx AX=________________
- 【其它】现有程序段如下: MOV BX, 23ABH ADD BL, 0ACH MOV AX , 23F5H ADD BH , AL SBB BX , AX ADC AX , 0012H 执行上述程序段后 AX= , BX= 。 (5.0分)
- 程序分析题 MOV AX,1234H MOV BX,AX NEG BX ADD AX,BX 请写出以上程序段执行后,(AX)=________。
- 执行如下操作后,(AX)= ()。 MOV AX, 0 MOV BX, 1 MOV CX, 100A: ADD AX, BX INC BX LOOP A
- 写出下列程序段执行后AX的值为多少? MOV AX, 1234H; AX=(1)H MOV CL, 4 AND AL, 0FH; AX= (2) H ADD AL, 30H; AX= (3)H SHL AH, CL; AX= (4)H AND AH, 0F3H; AX= (5)H
