Question

我有一个应该写入下面定义的gml文件的类。该类有一种方法可以完成写作。如果我调用该函数，我会在main函数返回时获得核心转储。我可以毫无问题地创建类的对象，它只在调用write函数时才会发生。该函数也会返回，没有错误，程序的其余部分也会运行。

GML作家：

class GMLWriter {
public:
    void write(List<User*> usr, const char* filename);
};

void GMLWriter::write(List<User*> usr, const char* filename)
{
    cout << "Filename: " << filename << endl;
    ofstream outfile;
    outfile.open(filename);
    if (!outfile.is_open())
        cout << "Couldn't open the file..." << endl;
    outfile << "graph [\n";

    // Write user data
    for (int n = 0; n < usr.size(); n++) {
        cout << "Writing node..." << endl;
        outfile << "node [\n";
        outfile << "id " << usr[n]->getID() << "\n";
        outfile << "name \"" << usr[n]->getName() << "\"\n";
        outfile << "age " << usr[n]->getAge() << "\n";
        outfile << "zip " << usr[n]->getZip() << "\n";
        outfile << "]\n";
    }

    // Write associations
    for (int n = 0; n < usr.size(); n++) {
        List<int> tList = usr[n]->getFriends();
        cout << "Writing edge..." << endl;
        //List<int> tempL = usr[n]->getFriends();
        for (int i = 0; i < tList.size(); i++) {
            outfile << "edge [\n";
            outfile << "source " << usr[n]->getID() << "\n";
            outfile << "target " << tList[i] << "\n";
            outfile << "]\n";
        }
    }

    outfile << "]"; // end graph
    cout << "End function" << endl;
    outfile.close();
}

用户只需包含要写入文件的变量，这些方法运行正常。

我已经在调试器中花了好几个小时，并且无法找到问题。任何帮助将不胜感激。

谢谢！
