Re: [問題] 想寫跟windows下的程式互動的C程式
我先寫了一個猜數字小遊戲:
http://nopaste.csie.org/a57f1
如你所見,這隻小遊戲真的很簡單
要破解這隻小遊戲
最好就是能得到 num 變數的值了
為了簡化問題,我把 &num 直接印出來
接下來,就是破解程式了
http://nopaste.csie.org/3353d
這是用 MSDN 拼湊出來的 XDD
執行的畫面大概是這樣的:

(若看不清楚,可按圖片下方的「看原始圖」)
可以看到確實可以很神準的把數字猜出來...XDD
這樣的小程式,應該可以算是個開始了
一定可以看得出來,我把許多地方都簡化很多
如果要破解的對象是「不知道記憶體佈局」的程式,就不會這麼輕鬆了
有興趣的可以繼續研究下去囉,也希望有其他強者可以繼續補充 XDDDD
ps. 我的編譯環境:Visual Studio 2010

對了,我想要請教一下
google 找到 scanf("%*c"); 這個東西可以吃掉 stdin 多餘的 \n
不過我不懂 "%*c" 的意思是...?
