#include <iostream>

#include <string>

#include <conio.h>

using namespace std;

//main function

int main()

{

string title;// book title

float price;// book price

int quantity;// book quantity

char ch;//choice

//input

cout<<"Enter the title of the book: ";

cin>>title;

cout<<"Enter the price of the book: ";

cin>>price;

cout<<"Enter the quantity to buy for the book: ";

cin>>quantity;

cout<<"Is 20% discount is provided for buying the book? (y/n)";

cin>>ch;

if(ch=='y'){//Is 20% discount is provided for buying the book

price=price-price*0.2;

double discountedprice=price*quantity;

//show result

cout<<title<<" discounted price for this book is

"<<price<<"

the total cost for buying the books at the

discounted price is $"<<discountedprice;
