[問題] Dev C++編碼錯誤訊息
看板C_and_CPP作者filexchang (LTE student researcher)時間9年前 (2014/09/12 12:20)推噓2(2推 0噓 0→)留言2則, 2人參與討論串1/1
現在碩四(中間因病休學兩次Q@Q)因此對程式有些生疏
可以請大大們幫我看看嗎Orz
以下是我寫的論文模擬程式碼(關於LTE MTC的)

cout<< countagent << endl;
}
我的錯誤訊息是顯示在最後一行
錯誤訊息是這個
[Error] expected '}' at end of input
可以請大大們幫我看看嗎Orz 上網google都只有英文的...
