I have a problem I'm not sure where the error is occurring. I think it's when I used cin.ignore in my code.
My problem is occurring in case A. For some reason the program stops right after I enter my price information. I tried doing small codes to figure where my problem is coming from. Everything works fine except the price variable. I am not sure why?
int main()
{
double amount;
char choice;
cout << "Please enter a starting amount in the store's cash registar:" << endl;
cin >> amount;
while(amount < 0)
{
cout << "Must enter a positive price. Please re-enter:";
cin >> amount;
}
cout << endl;
Store Bookstore(amount);
Menu();
do
{
cout << endl;
cout << "Enter your menu selection: ";
cin >> choice;
cin.ignore();
// Respond to the user's menu selection
switch (choice)
{
case 'a':
case 'A':
cout << "Please enter the information in the following order: title, author, genre, price" << endl;
char title[31], author[21], genre, gen;
double price;
cin.getline(title,31);
cin.getline(author,21);
cin.get(genre);
gen = CheckGenre(genre);
cin >> price;
Bookstore.AddBook(title, author, gen, price);
break;
case 'F':
case 'f':
cout << "Please enter title or author to search for a book in the inventory list"<< endl;
char selection[30];
cin.getline(selection,31);
Bookstore.FindBook(selection);
break;
case 'S:':
case 's':
cout << "Please type in the title of the book you would like to sell"<< endl;
char sold[31];
cin.getline(sold,31);
Bookstore.SellBook(sold);
break;
case 'D':
case 'd':
Bookstore.Inventory();
break;
case 'G':
case 'g':
cout << "Please input a genre"<< endl;
cout << "Please input a genre" << endl;
char genre2;
cin.get(genre2);
CheckGenre(genre2);
Bookstore.SumGenre(genre2);
break;
case 'M':
case 'm':
Menu();
break;
case 'X':
case 'x':
double money;
money = Bookstore.GetAmount();
cout << "$ " << setprecision(2) << fixed << right << money << endl;
return 0;
break;
default:
cout << "Incorrect selection, Please select a selection from the memu" << endl;
}
}
while (isalpha(choice));
return 0;
} // end main()
void Menu()
{
/* Declare your array and write the menu loop */
// Display the menu and get a choice
cout << "A: Add a book to inventory" << endl;
cout << "F: Find a book from inventory" << endl;
cout << "S: Sell a book" << endl;
cout << "D: Display the inventory list" << endl;
cout << "G: Genre summary" << endl;
cout << "M: Show this Menu" << endl;
cout << "X: eXit the program" << endl;
}
char CheckGenre(char genre)
{
while ((genre != 'F') && (genre != 'f') && (genre != 'M') && (genre != 'm') && (genre != 'S') && (genre != 's') && (genre != 'C') && (genre != 'c'))
{
cout << "Invalid genre entry. Please re-enter: ";
cin >> genre;
}
return genre;
}Also When did the Add function to work, The Inventory function would display that there is no bokk in the inventory.
Add Book Function
void Store::AddBook(const char* t, const char* a, char g, double p)

}Inventory Function

bookEntry[i].Display(); // send it to output
