student.h

这是编程之道C-C++中的源代码,很简练,可以用于相关教学和重新熟悉C-C++时使用

//定义并实现类CStudnet
#include "people.h"
#include <iostream.h >		//有些编译系统可能是包含iostream，并指明名字空间std;
#define MAXNUM 10			//MAXNUM为最多的课程数目

class CStudent:public CPeople
{
	float m_ArrayScore[MAXNUM];		//用来存放成绩的数组
protected:
	int		m_stuNo;			//学号
	int		m_courseNum;		//课程数目
	float	m_aScore;			//平均成绩

public:
	CStudent(int age,int No,int Num,char* pName ="no name"):CPeople(age,pName)
	{
		m_stuNo = No;
		m_courseNum = Num;
		m_aScore = 0.0f;

		//初始化成绩数组
		cout << "请输入学生" << m_pstrName <<m_courseNum <<"门课的成绩:"<<endl;
		for(int i=0;i<m_courseNum;++i)
			cin >> m_ArrayScore[i];
	}

	void CaculateAverageScore()
	{

	}

	float Getm_aScore(){return m_aScore;}
	friend ostream& operator<< (ostream& out,const CStudent& s); 
};
