【问题描述】:
我在这段代码中的目标是在列表中找到最小的数字。在这种情况下,我使用了冒泡排序方法;不幸的是,代码没有给我最小/最小的数字。请看一下,谢谢:
include irvine32.inc
.data
input byte 100 dup(0)
stringinput byte "Enter any string: ",0
totallength byte "The total length is: ",0
minimum byte "The minimum value is: ",0
.code
stringLength proc
push ebp
mov ebp, esp
push ebx
push ecx
mov eax, 0
mov ebx, [ebp+8]
L1:
mov ecx, [ebx] ;you can use ecx, cx, ch, cl
cmp ecx, 0 ;you can use ecx, cx, ch, cl
JE L2
add ebx, 1
add eax, 1
jmp L1
L2:
pop ecx
pop ebx
mov ebp, esp
pop ebp
ret 4
stringLength endp
BubbleSort PROC uses ECX
push edx
xor ecx,ecx
mov ecx, 50
OUTER_LOOP:
push ecx
xor ecx,ecx
mov ecx,14
mov esi, OFFSET input
COMPARE:
xor ebx,ebx
xor edx,edx
mov bl, byte ptr ds:[esi]
mov dl, byte ptr ds:[esi+1]
cmp bl,dl
jg SWAP1
CONTINUE:
add esi,2
loop COMPARE
mov esi, OFFSET input
pop ecx
loop OUTER_LOOP
jmp FINISHED
SWAP1:
xchg bl,dl
mov byte ptr ds:[esi+1],dl
mov byte ptr ds:[esi],bl
jmp CONTINUE
FINISHED:
pop edx
ret 4
BubbleSort ENDP
main proc
