Q7. Consider the following assembly code and write an equivalent C program to realize the same functions. (You can define the variable as the register) ASSUME CS:TT TT SEGMENT START: MOV BX,0 MOV CX,12 s: MOV AX,0FFFFH MOV DS,AX MOV DL, [BX] MOV AX,0020H MOV DS,AX MOV [BX],DL INC BX LOOP s MOV AX,4C00H INT 21H TT ENDS END Q8.
