我的任务是使用 3 个带参数的函数,如下所示:
函数 calcRegBill – 接受一个整数参数来表示使用的分钟数。确定并返回到期总金额。
函数 calcPremBill – 接受两个整数参数,分别表示使用的白天分钟数和夜间分钟数。确定并返回到期总金额。
函数 printBill – 接受 4 个参数:字符串帐号、字符服务代码、使用的整数总分钟数和到期金额。请注意,这是一个通用的打印账单功能,它使用以下格式打印普通账单或保费账单:
帐号:XXXX
服务类型:常规(或高级,取决于收到的字符)
总分钟数:XXX
应付金额:$XXX.XX
您的主要功能将提示用户输入帐号和服务代码。根据服务代码,main 将询问正确的分钟数,然后根据需要调用上面的函数来完成工作。此外,您必须:
在您的程序中加入一个循环,以根据需要多次运行账单。您可以通过哨兵控制循环或计数器控制循环来执行此操作。
我已经构建了程序并使用程序主要功能中的所有内容对其进行了测试。我真的很困惑如何将它分解为 3 个单独的功能并让它仍然有效。我是 C++ 的菜鸟
这是到目前为止的程序,我开始添加功能,但我不相信它们是正确的。
