代码说明：

一共使用了建造者模式、状态模式、命令模式、策略模式、单件模式这5个设计模式。本次课程设计是开发一款有多个面板的计算器。不仅有针对日常生活“标准型”面板、针对理工科计算的“科学型”面板、针对于编程人员计算“程序员”面板，还别出心裁地开发了针对中学生的数学学习“特色型”面板，有利于他们检查自己数学作业答案和试卷答案。本计算器实现了当点下拉菜单中标准型、科学型、程序员和特色型等选项可以切面不同的计算器面板。本计算器实现了当选中按钮时，按钮呈现如黄水晶般色调渐变的颜色。本计算器实现了自定义左上角图标的功能。关键词: 建造者模式状态模式命令模式策略模式单件模式计算器多面板标准型科学型程序员特色型初等函数二进制八进制十六进制分解质因数最简二次根式一元二次方程保留根号小数转分数循环小数(We used a total of builder mode, the state mode, command mode, the policy mode, single mode these five design patterns.

The calculator achieved her point standard drop-down menu, science-based, programmers and characteristics of different type and other options section of the calculator panel. This calculator implements the election of the button, the button showing topaz hue gradient colors. The calculator icon in the top left corner to achieve a custom function.

SPOOLING
要求设计一个SP00LING输出进程和两个请求输出的用户进程，以及一个SP00LING输出服务程序。当请求输出的用户进程希望输出一系列信息时，调用输出服务程序，由输出服务程序将该信息送入输出井。待遇到一个输出结束标志时，表示进程该次的输出文件输出结束。之后，申请一个输出请求块(用来记录请求输出的用户进程的名字、信息在输出井中的位置、要输出信息的长度等)，等待SP00LING进程进行输出。 SP00LING输出进程工作时，根据请求块记录的各进程要输出的信息，将其实际输出到打印机或显示器。这里，SP00LING输出进程与请求输出的用户进程可并发运行。 (Asked to design a user process SP00LING request output and two output processes, and outputs a SP00LING service program. When users want to process requests output output range information, call the output service program, service program by the output information into the output shaft. Treatment to an output end of the flag, which means that the process of the second output file output end. Thereafter, the application of an output request block (name of the user to record the output of the process request, the information on the position of the output well, and length information to be outputted), the process waits SP00LING output. When SP00LING output process work, information requested under each process block records to be output, its actual output to a printer or monitor. Here, the user process and the output process SP00LING request output can be run concurrently.)
