PTA-电信计费
目录
一、前言
1.难度分析
此次博客围绕6-8次PTA题目集（电信计费），难度在电信计费的三道题目上，主要是内容太多了，让人摸不着头脑，题目其实并不难（相较于前面那几道多边形的题目）。
2.题量分析
比前几次大作业要少，除了送分题就三道电信计费。
3.知识点
6-7-1 电信计费系列1-座机计费
1、月租20元，接电话免费，市内拨打电话0.1元/分钟，省内长途0.3元/ 分钟，国内长途拨打0.6元/分钟。不足一分钟按一分钟计。
2、南昌市的区号：0791，江西省内各地市区号包括：0790~0799以及0701。
3、座机号码由区号和电话号码拼接而成，电话号码包含7-8位数字，区号最高位是0。座机号码有以下两种类型：
(1)区号：4位 电话号码：8位
(2)区号：3位 电话号码：7位
4、时间必须符合"yyyy.MM.dd HH:mm:ss"格式（如2022.1.3 10:00:25），建议使用SimpleDateFormat类编写代码。
5、每个用户初始余额是100元。计算所有已开户的用户的当月费用（精确到小数点后2位，单位元），没有开户的用户不能计算费用。
6、注意，题目提到不检查“开户号码非南昌市的号码”这种情况，也就是说用不是南昌的座机区号开通用户也是正确的（至少在这里）。除了存在4位的座机区号外，还有3位的座机区号（如北上广），区分是3位的号码长度是10位，也就是上面知识点3中的类型（2）。
7-7-1 电信计费系列2-手机+座机计费
除了座机计费的知识点或者说内容点以外，增加了“手机计费”的以下几点：
1、月租15元，市内省内接电话均免费，市内拨打市内电话0.1元/分钟，市内拨打省内电话0.2元/分钟，市内拨打省外电话0.3元/分钟，省内漫游打电话0.3元/分钟，省外漫游接听0.3元/分钟，省外漫游拨打0.6元/分钟。
个人理解：每个月要交15元月租，只有在省外接别人的电话才需要计费，市内和省内打电话都是0.3元/分钟，在省外打电话是0.6元/分钟。
2、被叫电话属于市内、省内还是国内由被叫电话的接听地点区号决定，比如以下案例中，南昌市手机用户13307912264在区号为020的广州接听了电话，主叫号码应被计算为拨打了一个省外长途，同时，手机用户13307912264也要被计算省外接听漫游费：
u-13307912264 1
t-079186330022 13307912264 020 2022.1.3 10:00:25 2022.1.3
10:05:11
个人理解：看代码说话，第一行代码表示在南昌（题目默认）开通手机用户13307912264，第二行代码表示手机用户（13307912264）在区号为020（广州）接听了来自南昌的座机（079186330022）的来电。在这种情景下南昌的座机（079186330022）要以省外拨打电话为计费标准，而手机用户（13307912264）就要以省外接听电话为计费标准，虽然手机用户是在南昌开通的，但是他漫游到了广州，对于南昌来说就是省外。
3、手机号码由11位数字构成，最高位是1。
8--1 电信计费系列3-短信计费
1、计费方式：接收短信免费，发送短信0.1元/条，超过3条0.2元/条，超过5条0.3元/条。如果一次发送短信的字符数量超过10个，按每10个字符一条短信进行计算。
个人理解：结合下面的计费代码来看，先计算有多少条短信，然后根据短信的条数计费。
double sumCost = 0;//计费总金额
int number = 0;//短信条数
//遍历所有的发送记录
for (MessageRecord m : userRecords.getSendMessageRecords()) {
//单条短信的字符数量
int length = m.getMessage().length();
if (length <= 10) {//字符不超过10个
number++;//算作一条
} else {//字符超过10个
number += length / 10;//先取十位数相加
if (length % 10 != 0) {//再看个位数，不为0加1
number++;
}
}
}
//按总的短信条数计费
if (number <= 3) {//0-3条0.1元/条
sumCost = number * 0.1;
} else if (number <= 5) {//3-5条0.2元/条
sumCost = 0.3 + 0.2 * (number - 3);
} else {//超过5条0.3元/条
sumCost = 0.7 + 0.3 * (number - 5);
}
return sumCost;

采坑心得
基本上没什么坑，注意座机区号有三位就行。
改进建议
电信计费题的框架都是老师给出来的，感觉没什么改进的。另外的送分题简单，大多也有框架。
总结
总的来说，第6-8次大作业是比前面的大作业轻松一个量级的，非说有什么困难的话，内容多，需要挺长的时间去理顺老师的类图框架。
