[C++知识库]C++上机实验4

#pragma once
#include <iostream>
using namespace std;
class student
{
public:
	void InitStudent(char name[]);
	void ExpendMoney(float a);
	void ShowMoney();
private:
	static float m_ClassMoney;
	char nm[20];
};
float student::m_ClassMoney = 1000;
void student::InitStudent(char name[])
{
	int i = 0;
	while (name[i])
	{
		nm[i] = name[i];
		i++;
	}
}
void student::ExpendMoney(float a)
{
	m_ClassMoney += a;
}
void student::ShowMoney()
{
	cout << "班费还剩" << m_ClassMoney << endl;
}
int main()
{
	student A, B, C;
	A.ExpendMoney(-50);
	A.ShowMoney();
	B.ExpendMoney(-98.5);
    A.ShowMoney();
	C.ExpendMoney(-500.53);
    A.ShowMoney();
}

本次C++实验主要学习学习对象传递与静态成员功能，进一步加深了对类与对象的理解，掌握了静态成员的概念和使用，同时创建了student类initstudent，expendmoney和showmoney来实现显示剩余班费的功能。程序代码和实验结果如上。
