基于SignalR的聊天室

1、设计一个程序，其中有3个类，即CBank，BBank和GBank，分别为中国银行类、工商银行类和农业银行类。每个类都包含一个私有数据balance，用于存放储户在该行的存款数，另有一个友元函数total用于计算储户在这3家银行中的总存款数。 2、设计一个程序，其中有2个类，Point类为点类，包含2个私有数据x和y，表示点的坐标，line类为直线类，包含3个私有数据a，b和c，表示直线方程ax+by+c=0。另有一个友元函数dist，用于计算一个点到直线的距离。点与直线之间的距离计算公式如下：(提示：本题为有元函数的应用) -1, design a program, of which three categories, namely CBank, BBank and GBank, respectively, for the Chinese banking, business banking and agricultural banking. Each class contains a private data balance, used to store the bank deposits of savers in the number, while a friend function used to calculate the total depositors in the three the number of total deposits in banks. 2, design a program, of which there are 2 categories, Point class for the point class, including two individual and private data are x and y, that the coordinates of points, line for line class categories, with three individual and private data are a, b and c, that straight line equation ax+ by+ c = 0. There is also a friend function dist, used
