[問題] visual studio2008 自行輸入變數有問題
小弟正在看Compiler Construction 這本書
作者是 Kenneth C.Louden
目前照著書上範例程式逐步執行
工具用的是visual c++2008

如圖所示小弟把argc這變數改成2，所以它會跳過if (argc != 2)這裡面的內容
並且執行 strcpy(pgm,argv[1]) ; 但是卻突然跑出左邊中間那個視窗說我存取違規
希望可以請各位前輩指導小弟這是什麼原因並且告訴我該怎麼把這狀況排除
感激不盡!!!
PS:我在想是不是因為程式不知道argv[1]的內容是什麼，或著是因為pgm已經有放東西了
是這樣嗎?
