所以我写了“tic tac toe”主机游戏。它读取播放器的名称并将它们存储在文本文件中，并显示（或应该显示）文本文件中所有播放器的列表。但它不会显示所有玩家的名字。如果我直接选择显示名称选项（即案例 2），它不会显示任何内容。如果我玩游戏一次并按两个它只会显示当前 2 个玩家的名字。我希望它显示该列表中所有玩家的姓名！这是我的代码（查看 main () 中的案例 2），案例 3 也显示了意想不到的结果。请帮助

将 rdbuf 添加到第二种情况。您的代码应如下所示：

case 2:
    {

        ifstream infile("file.txt",ios::in);
        cout<<"The name of players are "<<endl<<player1<<"\t"<<player2<<endl;;
        **cout << infile.rdbuf()<<endl;**
        cout<<endl<<endl<<endl;
        main ();
    }

rdbuf读取所有文件并在您的帮助下cout将内容转储到控制台

还可以将播放器名称写入文件修改 user_info，如下所示：

void user_info ()
{
    ofstream infile("file.txt",ios::app);
    cout<<"player 1 enter your name :";
    cin>>player1;
    infile << player1;
    cout<<"\n\nplayer 2 enter your name :";
    infile << player2;
    cin>>player2;

    cout<<endl<<endl;
    cout<<player1<<"'s symbol is 'O'\n\n";
    cout<<player2<<"'s symbol is 'X'\n\n";
    cout<<endl<<endl;
    infile<<player1<<"\t"<<player2<<endl;

}
