第三阶段Blog作业
题目集7-1 图形卡片排序游戏
输入格式:
- 首先，在一行上输入一串数字（1~4，整数），其中，1代表圆形卡片，2代表矩形卡片，3代表三角形卡片，4代表梯形卡片。各数字之间以一个或多个空格分隔，以“0”结束。例如： 1 3 4 2 1 3 4 2 1 3 0
- 然后根据第一行数字所代表的卡片图形类型，依次输入各图形的相关参数，例如：圆形卡片需要输入圆的半径，矩形卡片需要输入矩形的宽和长，三角形卡片需要输入三角形的三条边长，梯形需要输入梯形的上底、下底以及高。各数据之间用一个或多个空格分隔。
- 如果图形数量非法（小于0）或图形属性值非法（数值小于0以及三角形三边不能组成三角形），则输出Wrong Format。
- 如果输入合法，则正常输出，所有数值计算后均保留小数点后两位即可。输出内容如下：
输出格式:
- 排序前的各图形类型及面积，格式为图形名称1:面积值1图形名称2:面积值2 …图形名称n:面积值n ，注意，各图形输出之间用空格分开，且输出最后存在一个用于分隔的空格；
- 排序后的各图形类型及面积，格式同排序前的输出；
- 所有图形的面积总和，格式为Sum of area:总面积值。

这道题没有想象中那么复杂，和前面有一次的图形继承差不多，只是在原来的基础上增加了在输入输出上的难度，也将每个图形都分好了类，没有特别的地方。

- 输出分组后的图形类型及面积，格式为[圆形分组各图形类型及面积][矩形分组各图形类型及面积][三角形分组各图形类型及面积][梯形分组各图形类型及面积]，各组内格式为图形名称:面积值。按照“Circle、Rectangle、Triangle、Trapezoid”的顺序依次输出；
- 各组内图形排序后的各图形类型及面积，格式同排序前各组图形的输出；

这道题在前面的那题的基础上没有太大改动，加入了分组元素，每个图形组的输入输出都归结到一起，其实也没有那么复杂，因为有前面的基础写起来还是很容易的。
题目集8 ATM机类结构设计（一）
输入格式:
每一行输入一次业务操作，可以输入多行，最终以字符#终止。具体每种业务操作输入格式如下：
- 存款、取款功能输入数据格式： 卡号 密码 ATM机编号 金额（由一个或多个空格分隔）， 其中，当金额大于0时，代表取款，否则代表存款。
- 查询余额功能输入数据格式： 卡号
输出格式:
①输入错误处理
- 如果输入卡号不存在，则输出Sorry,this card does not exist.。
- 如果输入ATM机编号不存在，则输出Sorry,the ATM's id is wrong.。
- 如果输入银行卡密码错误，则输出Sorry,your password is wrong.。
- 如果输入取款金额大于账户余额，则输出Sorry,your account balance is insufficient.。
- 如果检测为跨行存取款，则输出Sorry,cross-bank withdrawal is not supported.。
②取款业务输出
输出共两行，格式分别为：
[用户姓名]在[银行名称]的[ATM编号]上取款¥[金额]
当前余额为¥[金额]
其中，[]说明括起来的部分为输出属性或变量，金额均保留两位小数。
③存款业务输出
输出共两行，格式分别为：
[用户姓名]在[银行名称]的[ATM编号]上存款¥[金额]
当前余额为¥[金额]
其中，[]说明括起来的部分为输出属性或变量，金额均保留两位小数。
④查询余额业务输出
¥[金额]
金额保留两位小数。

分析
这道题有点棘手，好在之前做过一个银行取钱的题目，用户账户也很大程度的得到进一步的扩展，没有做过这方面的深入，刚开始做起来还是很困难的，所以在使用类方法的时候没有考虑很多，很多地方都有更简便的算法，后来也没有纠结那么多。
题目集9 ATM机类结构设计（二）
输入格式:
每一行输入一次业务操作，可以输入多行，最终以字符#终止。具体每种业务操作输入格式如下：
- 取款功能输入数据格式： 卡号 密码 ATM机编号 金额（由一个或多个空格分隔）
- 查询余额功能输入数据格式： 卡号
输出格式:
①输入错误处理
- 如果输入卡号不存在，则输出Sorry,this card does not exist.。
- 如果输入ATM机编号不存在，则输出Sorry,the ATM's id is wrong.。
- 如果输入银行卡密码错误，则输出Sorry,your password is wrong.。
- 如果输入取款金额大于账户余额，则输出Sorry,your account balance is insufficient.。
②取款业务输出
输出共两行，格式分别为：
业务：取款 [用户姓名]在[银行名称]的[ATM编号]上取款¥[金额]
当前余额为¥[金额]
其中，[]说明括起来的部分为输出属性或变量，金额均保留两位小数。
③查询余额业务输出
业务：查询余额 ¥[金额]
金额保留两位小数。

分析：
和上一题基本相同，难度也有了一定提升，但是在上一题的基础上修改代码就容易很多了，和上一题相比这道题加入了账号种类，加入了借贷功能，也加入了一些用户数据，其他方面就没有太大改变。
