根据消费者购买的东西计算电脑商店的账单，我有一个非常令人困惑的问题。可供选择的事项如下：
* The base package cost is $599 and includes 4 GB of memory,
a 512Gb Hard Drive and a 21" LED monitor.
Permitted upgrades to the base system add the following costs:
+ Upgrade to 8 GB or 12 GB of Memory adds $99 and $189 respectively.
+ Upgrade to 27" LED monitor adds $199.
+ Upgrade to a 128 GB SSD adds $119.
+ NO Video card upgrade possible for the base package.
* The professional package cost is $899 and includes 8 GB of memory,
a 1TB Hard Drive and a 27" LED monitor.
Permitted upgrades to the professional system add the following costs:
+ Upgrade to a maximum 16 GB of Memory adds $189.
+ Upgrade to 32" LED monitor adds $199.
+ Upgrade to a 256 or 512 GB SSD adds $189 and $399 respectively.
+ Upgrade to a discrete 2GB Video card adds $209.
* The game package cost is $1499 and includes 16 GB of memory,
a 256 SSD Drive, a 32" LED monitor, and a discrete 2 GB Video card.
Permitted upgrades to the game system add the following costs:
+ Upgrade to a maximum 32 GB of Memory adds $389
+ Upgrade to 28" 4K HD monitor adds $299
+ Upgrade to a 512 GB or 1 TB SSD adds $299 and $599 respectively.
+ Upgrade to a discrete 4GB Video card adds $399.
如果消费者在购买任何电脑后做出某些修改，我如何计算整体账单？
到目前为止，我已经编写了以下程序，但这似乎并不顺利。

你应该使用addOn的布尔数组，而不是声明3个不同的变量。并进行任何修改使用功能。
1）喜欢买（）
2）修改（）
3）打印（）
使用sum变量，它将计算总成本。每当要修改账单时，只需将sum（）作为参数发送到Modify（），然后从总和中添加或减少。
这是一个简单的方法试试吧。并确保检查，以便客户无需购买东西即可使用Modify（）！

首先，使用数组来存储插件。并使用（用户输入 - 1）作为数组索引;
您没有添加价格。在每个检查用户输入的if语句中，也要添加价格。
price = 0
if(addon1 == 1)
{
printf("8 GB Memory: \t 99.00\n");
price += 99.00;
}
else if(addon1 == 2)
{
printf("12 GB Memory: \t 189\n");
price += 189.00
}
.................. 等等。
