我的手机账单项目C ++存在问题 [英] I have an issue with my cell phone bill project C++

问题描述

当用户选择常规电话帐单服务时，似乎会出现问题，但它没有提供正确的输出。高级电话费对我有用，唯一棘手的泡菜是普通电话费服务。



我尝试过：

The issue seems to arise when the user select the regular phone bill service it doesn't give a proper output. The premium phone bill worked for me the only tricky pickle is the regular phone bill service.

What I have tried:

#include <iostream>

#include <iomanip>
//Made By Lee Rankin
/*

Write a program that calculates and prints the bill for a cell phone company.  The company offers two types of service: regular and premium.  Its rates vary, depending on the type of service.
The rates are computed as follows:

Regular service: $10.00 plus 50 minutes are free.  Charges for over 50 minutes are $.20 per minute.

Premium service: $25.00 plus:

a. For calls made from 6:00 a.m. to 6:00 p.m., the first 75 minutes are free; charges for over 75 minutes are $0.10 per minute.

b. For calls made from 6:00 p.m. to 6:00 a.m., the first 100 minutes are free; charges for over 100 minutes are $0.05 per minute.

Your program should prompt the user to enter an account number, a service code (type char), and the number of minutes the service was used.
A service code of R or r means regular service; a service code of P or p means premium service.  Treat any other character as an error.
Your program should output the account number, type of service, number of minutes the telephone service was used, and the amount due from the user.

For the premium service, the customer may be using the service during the day and the night.
Therefore, to calculate the bill, you must ask the user to input the number of minutes the service was used during the day and the number of minutes the service was used during the night.
