C++程序实现交易应用

交易是一个涉及购买和销售货物和服务的主要经济概念，以及买方向卖方支付的补偿。在C ++中建立交易应用程序可以作为了解C ++基本概念的好例子。此外，对于初学者来说，它可以作为迷你项目，帮助他们增强对C ++的理解，并在初始阶段构建他们的简历。

问题陈述：

在C++中构建交易应用程序，其中执行的操作如下：

获取帐户信息
存款
取款
购买加密货币
出售加密货币
检查交易

要执行的操作

交易包括有关利润损失和货币的知识。因此，程序的变量如下：

用户余额
利润损失检查器
比特币和狗币
选择
取款金额
预测
总资产净值

现在来看一下我们将执行的操作：

1. 获取帐户信息：

在此操作中，我们只需打印有关用户帐户的信息，即我们要观察的所有变量是利润损失，货币，金额等。

2. 存款：

在存款中，我们可以将钱存入我们的帐户中。

3. 取款：

在取款中，我们可以取出我们帐户中的钱。

4. 购买加密货币：

我们将使用此操作购买加密货币。根据我们的需求，我们可以购买比特币或狗币。

5. 出售加密货币：

我们将出售加密货币，并将售出后获得的金额加入我们的帐户。

6. 检查交易：

在此操作中，我们将打印迄今为止执行的所有交易。
