一、教学目的： 能理解C++中运算符重载的需要性

#ifndef savings
  #define savings

class Savings
{
public:
	Savings(unsigned accNo,float balan=0.0);
	unsigned AccountNo();
	float AcntBalan();
	static Savings* First();
	Savings* Next();
	static int NoAccounts();
	void Display();
	void Deposit(float amount);
	void Withdrawal(float amount);
protected:
	static Savings* pFirst;
	Savings* pNext;
	static int count;
	unsigned acntNumber;
	float balance;
};
#endif
