For a program I'm making the user needs to enter a string and then it will be checked to see if it is a palindrome. So far I've managed to reverse the ordering of the string entered so that I have the original string and the reverse version of it.
The problem is that I don't know how to compare these two strings.
Please if you can help me I would appreciate it.
CR equ 13 LF equ 10 JMP START prompt db CR,LF,'Please enter a word to be checked: $' outmsg db CR,LF,'The reverse word is: $' instring db 12,?,' $' outstring db '????????????$' correct db CR,LF,'The word that you have entered is a palindrome$' incorrect db CR,LF,'The word that you have entered is not a palindrome$' firstchar dw ? START: LEA DX,prompt MOV AH,9 INT 21h LEA DX,instring MOV AH,0ah INT 21h LEA SI,instring MOV BL,byte ptr[SI + 1] INC BL MOV BH,0 ADD SI,BX LEA firstchar,instring+2 LEA DI,outstring MOVECHAR: MOV BH,byte ptr[SI] MOV byte ptr[DI],BH CMP SI,firstchar JE DONE DEC SI INC DI JMP MOVECHAR DONE: INC DI MOV byte ptr[DI],'$' LEA DX, outmsg MOV AH,9 INT 21h LEA DX,outstring MOV AH,9 INT 21h FINISH: MOV AH,4ch INT 21h
