分割錯誤打開文件

我只是想學習C http://fromlearncodethehardway.com開始。不過，我在嘗試對其中一個示例進行編碼時遇到了分段錯誤。指向我的源代碼的鏈接。我嘗試使用valgrind進一步幫助調試，但我似乎無法弄清楚這個問題。這是來自valgrind的堆棧跟蹤。分割錯誤打開文件

調試的任何幫助將是偉大的。謝謝！

請在此處顯示您的代碼。請勿鏈接到其他網站。 – 2012-04-19 17:41:08

嘗試將您的問題減少到更小的測試用例，並在此處包含您的代碼。 – 2012-04-19 17:41:29

在Stack Overflow上使用Pastebin絕對是一個新手錯誤。 – chrisaycock 2012-04-19 17:41:47

在您的代碼中，您有fopen調用爲fopen(filename,'w'); & fopen(filename,'r+');。那些應該是fopen(filename,"w"); & fopen(filename,"r+");。第二個參數fopen應該是const char *
希望這有助於！

順便說一下，我認爲你的意思是http://c.learncodethehardway.org/
你給的地址沒有解決。
