No matching function for call to getline()?
每当我尝试建立这段程式码时,都会发生错误,
"No matching function for call to getline()"
但是我以前用过它,效果很好吗? S我不确定发生了什么。 如果可以的话,我正在使用Mavericks OSX,并使用Xcode构建该项目。 是上学的 我知道inputFile可以正常工作,因为我已经注释了getline()和打印到控制台的"打开"。

第三个参数是单个字符,因此您需要
1 | getline(inputFile, headings[0][0], '*'); |
请注意单引号。
