我補上我的全部程式 http://codepad.org/l647UDbI
http://ppt.cc/iXL8
這個是我參考的網址
裡面說到"陣列長度必須事先決定，所以您不可以使用變數來事後決定陣列的長度"
可是比方說我寫一段程式:
int plength; /* plength表示密碼的長度*/
printf("length=?\n"); /*印出length=? */
scanf("%d",&plength); /*抓我的輸入當作密碼長度*/
int realpassword[plength]; /*正確密碼是這個陣列 長度是我的輸入*/
這樣 compiler不會有錯誤 執行起來也是正確的...
可是我用了會變動的陣列 是我運氣好pass了嗎?
ps. 抱歉沒有用預定的格式po...因為不是很完整的問題...
