我正在做一个数据结构项目，编写我自己的模板链表类实现很重要，它要求： 每个签证账户都可以使用签证卡进行交易，交易记录在他的账户中，包括到期日和金额。
我的步骤：
列出系统中的帐户。
每个帐户都有自己的卡片列表，因为需要签发另一张不同号码但需要同一帐户的签证卡。
为每个签证制作一份交易清单。
我的问题：
2.余额＆＃34;所有交易的总和＆＃34;没有更新，我稍后需要它让用户付款。
注意：主要没有完成，还有另外一个数据，我需要做其他功能尚未完成，所以没有问题，如果你发现多余的参数。 我还没有提前或后期条件。

编辑部分： 1.将节点类中的所有数据更改为指向数据的指针
2
card * list<T>::getcard(int i, string p)
{

while (temp != nullptr)
{

return &c;
}
解决部分是有一个事务列表，其中保存了不同的事务，但帐户列表和卡列表有问题： 如果我将约翰添加到帐户然后乔 它将有两个名为joe的帐户。 和卡片列表相同的问题
