Question

我收到这些错误，我不明白为什么，程序在学校编好而不是它的疯狂，任何人都可以翻译吗？

functions.cpp: In function 'void printCreatures(Creatures*, int)':
functions.cpp:248:35: error: no matching function for call to 'std::basic_fstrea
m<char>::open(std::string&, const openmode&)'

编辑：第241 -258行我将再次编辑并在几分钟后添加其余内容。

if (menuOption == '2')
    {
        cin.ignore();
        cout << endl << "What is the name of the file you wish to write to? ";
        getline(cin, filename);

        // attempt to open the file.
        dataFile.open(filename, ios::out);

        if (dataFile.fail())    
            cout << endl << endl << "Failed to create " << filename 
                << ", unable to save creatures - file already open?" << endl << endl;
        else
        {
            cout.rdbuf(dataFile.rdbuf());
            redirected = true;
        }
    }

如果使用C ++ 11兼容性进行编译，则只能使用fstream直接打开

std::string，在编译时添加-std=c++11标志或通过调用{{打开文件1}}你的字符串的功能。
