		 Unit_Price = u;
	}
	void printCurrentDetails(){
		cout<<"Book ID: "<<Book_ID<<"\nTitle: "<<Title<<"\nAuthors: "<<Authors<<"\n Unit Price: "<<Unit_Price<<endl;
	}
	void updatedDisplay(int price){
		Unit_Price =  price;
cout<<"Book ID: "<<Book_ID<<"\nTitle: "<<Title<<"\nAuthors: "<<Authors<<"\n Unit Price: "<<Unit_Price<<endl;
	
	}
	void totalamountPaid(){
		cout<<"The total price paid is:\t"<<Unit_Price + (Unit_Price * 0.12)<<endl;
	}
};
