stock2.h

我学习C++ Primer Plus过程中写下的课后作业的编程代码

// stock2.h -- augmented version
#ifndef STOCK_H_
#define STOCK_H_

class Stock
{
private:
	char	*company;
	int		shares;
	double	share_val;
	double	total_val;
	void set_tot(){ total_val = shares * share_val; }
public:
	Stock();
	Stock( const char * co, int n = 0, double pr = 0.0 );
	Stock( const Stock & s);
	Stock & operator = (const Stock & s);
	~Stock();
	void buy (int num, double price);
	void sell (int num, double price);
	void update (double price);
	const Stock & topval (const Stock & s)const;
	friend std::ostream & operator<< (std::ostream & os, const Stock & s);
};
