ifstream 始终将"ELF"返回到对象

我写了下面的方法来检查我的程序是否正确地处理文件IO，但它绝对不起作用。我从inFile得到的都是"ELF"，有人能告诉我为什么吗?我的对象可以很好地与其他类型的流兼容。

void testFiles(int ct, char ** args)
{
    if(ct<2){
        cout<<"Invalid number of arguments. Must be two files, one for input, one for output."<<endl;
        return;
    }
    ifstream inFile;
    inFile.open(args[0]);
    Tree<Word,int> x;
    Word *key;
    Word *val;
    cout<<"Tree extracted from file: "<<endl;
    while(inFile.good()&&inFile.is_open()){
        key = new Word();
        val = new Word();
        inFile>>*key;
        inFile>>*val;
        if(!inFile.good()){
            cout<<"Error: incomplete key-value pair:"<<key->getStr()<<endl;
            break;
        }
        cout<<key->getStr()<<" "<<val->getStr()<<endl;
        x[*key] = val->asInt();
        delete key;
        delete val;
    }
    inFile.close();
    ofstream outFile;
    outFile.open(args[1]);
    cout<<"Tree as read from file:"<<endl<<x;
    outFile<<x;
    outFile.close();
}
