/* Demonstration of getline with strings combined with cin for numbers
and string resizing */

#include <iostream>
#include <iomanip>
#include <string> // Don't forget this #include

using namespace std;

int main()
{

int quantity = 0; //It's a good habit to initialize your variables
double price = 0.0;
string title = " ";
string ISBN = " ";
string dAte = " ";

//INPUT---------------------------------------------------------------------------------------

cout << "Please enter a Book Title: ";
getline(cin, title); // Use getline to input a full string including spaces

cout << "\nPlease enter a Quantity: ";
cin >> quantity; // Use cin to input numbers
cin.ignore(); // This line tells the program to ignore any input
// that may be "leftover" from the cin statement. cin
// will leave behind a \n when the enter key is hit.
// Therefore, when using cin and getline together,
// you must use cin.ignore() after a cin statement to
// ensure any future getlines work propoerly.

cout << "\nPlease enter an ISBN: ";
getline(cin, ISBN); // This getline will not work without the cin.ignore() above

cout << "\nPlease enter a Price: ";
cin >> price;
cin.ignore();

cout << "\nPlease enter a DATE: ";
getline(cin, dAte);

//OUTPUT-----------------------------------------------------------------------------------------

//The following output is formatted but does not check for excessive string length like
//long titles

//long titles

if (title.length() > 24) //You may check the length of a string including spaces this way
title.resize(24); //If the string is too long, you can truncate it this way
if (ISBN.length() > 19)
ISBN.resize(19);

}
cout << " -----------------------------------------------------------------------------" << endl << endl;

// My Problem is here, how do I get this cout option initialized so
// that it works and takes the user back to the prompts of entering ISBN, DATE,
// PRICE, QUANTITY, etc.
// While also giving the user the No (N) option to exit the program entirely.
