C++11 C++。txt读入问题。getline读取完整文件

首先，请原谅我的代码很丑。在所有潜在的解决方案都不起作用之后，我得到的试图修复这段代码的大量想法把它弄得一团糟。基本上，我正在编写一个炉石翻版，它读取两个包含卡信息的.txt文件，并与它们战斗，以查看哪个玩家获胜。问题是，当我试图保存玩家的名字（文件中的第一行）时，它会保存整个文件，而不仅仅是第一行。当我设法解决这个问题时，由于某种原因，用于保存卡对象信息（格式：卡名称、卡电源、卡运行状况）的for循环无法正确保存。任何帮助都将不胜感激，我已经试着解决这个问题两天了，但没有任何东西能完全解决这个问题。我将在代码之前先附加读入文件

免责声明：有很多行，对此我很抱歉。此外，我认为问题可能是我的Mac电脑没有将.txt保存为具有正确行结尾的格式。我正在使用XCode作为我的IDE。非常感谢任何愿意帮忙的人

主要内容：

#包括“Player.h”
使用名称空间std；
int main（）
{
cout您的代码几乎正确。它可以读取玩家的姓名和卡号，但您的代码显示如下：

in>>numCards;
playerName = "";
numCards = 0;
cards = new Card* [numCards];

首先，它读取卡的num并将其存储到numCards，这是正确的。
接下来，您清除numCards的值，然后，您丢失了卡的num，因此它后面的代码将以
numCards==0执行
您只需注释行
numCards=0
，代码就会正确执行
