有一个圆环，其中小院半径为2.5，大圆半径为7。编程定义一个circle类，含有私有变量半径r，能够初始化r，计算圆面积。主函数中通过定义2个对象（大圆和小圆）来计算出圆环的面积。(There is a circle, of which the radius is 2.5 and the radius is 7. Programming defines a circle class, which contains the private variable radius R. It can initialize R and calculate the circle area. In the main function, the area of the circle is calculated by defining 2 objects (large circles and small circles).)

仿真计算银行服务系统的顾客平均等待时间，可以修改程序参数（如顾客出现概率，最大服务时间，服务窗口数等）来计算顾客平均等待时间。(The average customer waiting time simulation system of banking services, you can modify the program parameters (such as customer probability, maximum service time, service number of windows, etc.) to calculate the average customer waiting time.)
