Experiment topic 2自定义字符串类示例程序：#include<iostream>using namespace std;const int n=256;class mystring{ char str[n]; //存放字符串的数组容器，可考虑定义指针，在构造函数中动态分配空间 int maxsize; //最大可用元素数，可防止...

[Experiment topic 3]**class Student//学生结点类{long no;char *name;int score;Student link;public:Student(long nno,char nn="",int score1=0,Student next=NULL){name=new char[strlen(nn)+1];no=nno;sc...

[Experiment topic 2]用编辑器（记事本等）产生一个文本文件data.txt，其内容为若干实数，数据之间以空白字符分割。编程从该文件中读入这些实数，求出这些实数的平均值，在程序中创建并产生一个文本文件result.txt，内容为data.txt中的全体实数，每行5个数，最后一行是求出的平均值。 Experimental procedure#include<iostream>#include<fstream> //file I/O support#inclu

熟练掌握用程序直接读取文件中的数据而不是手工输入。Master how to use program to read the data in the file directly instead of inputting manually.学会让程序将输出写入到文件从而得到有关结果的永久性记录。Learn to have the program write output to a file to get a permanent record of the results.[Experiment t.

以点(point)类为基类(不必和上题点类完全一致)，定义派生类：矩形类和圆类。点为直角坐标点，矩形水平放置，由左下方的顶点和长宽定义。圆有圆心和半径定义。派生类操作判断任一坐标点是在图形内，在图形的边缘上，还是在图形外。默认初始化图形退化为点。要求包括拷贝构造函数。编程测试类是否正确。1. Experimental procedure#include<iostream>...

[Experiment topic 1]定义一个点类，如下：class Point{int x,y;static int countp;//统计点对象个数public:Point(int x=1,int y=1);void Setxy(int xx,int yy);void Getxy(int &xx,int &yy);//引用参数有什么作用?static in...
