//1、本章只为了刷存在演习。。
。

typedef struct phone
{
	char * quhao;
	char * jiaohuantai;
	char * zhanhaoma;
};

typedef struct call
{
	char * date;
	char * time;
	phone * shiyong;
	phone * self;
	phone * hujiao;
};
2、
typedef struct cash
{
	float retail_price;
	float actual_price;
	float sales_tax;
	float licensing_fee;
};
typedef struct daikuan
{
	float retail_price;
	float actual_price;
	float sales_tax;
	float licensing_fee;
	float doun_payment;
	float loan_duration;
	float interst_rate;
	float monthly_payment;
	float name_of_bank;
};
typedef struct zulin
{
	float retail_price;
	float actual_price;
	float down_payment;
	float security_deposit;
	float monthly_payment;
	int lease_term;
};

typedef struct sale
{
	char name[20];
	char address[40];
	char model[20];
	union  
	{
		cash trade;
		daikuan trade;
		zulin trade;
	};
