c++如何从txt里面调取文本的每一行当做储存位置到这个函数里面？

[qq_37057170]

函数如下：
void Song::playSong()
{
TCHAR fileName[255];
MultiByteToWideChar(CP_ACP, 0, path.c_str(), -1, fileName, strlen(path.c_str()));
TCHAR shortName[255];
GetShortPathName(fileName, shortName, 1000);
TCHAR cmd[256];
wsprintf(cmd, L"play %s repeat", shortName);
mciSendString(cmd, NULL, 0, NULL);
}
