調用getline（）沒有匹配的函數嗎？

Question

每次我嘗試建立這個代碼我得到一個錯誤，

「爲號召函數getline不匹配功能（）」

但我之前已經用它和它好工作？ S我不確定發生了什麼事。我使用Mavericks OSX，如果這是任何事情，並使用Xcode來建立這個項目。這是學校。我知道inputFile工作正常，因爲我已經評論了getline（）和「打開」打印到控制檯。

    getline(inputFile, headings[0][0], "*");

    return 0;

Answer 1

第三個參數是一個字符，所以你需要

getline(inputFile, headings[0][0], '*'); 

注單引號。 "*"是一個以NULL結尾的字符串文字，類型爲const char[2]。
