I am having troubles with my DVD collection assignment. I can get it to do most everything, but when I add any more than two DVDs, it wont save the extras. For example, I inputted four classes into my vector(list) with titles as "lalaland", "frosty", "adorable puppies", and "alpha". When I go to display the contents (menu item 1) it lists:
1. lalaland
2. frosty
3. lalaland
4. frosty
Is there a way to create a new class every time addDVD is called?
Also my selection sort does nothing. cant figure that one out either. Any recommendations would be very helpful.
#include "DVD.h"
int displayMenu();
void selectionSort(vector<DVD> &);
void addDVD(DVD&);
bool again = true; //see the menu again
char over; //would you like to run throught he case again?
bool OVER = false;
int selection, index, c = 0;
vector<DVD> list(0); //create the library starting with empty
DVD movie1;
void main()
{
cout << "Hello. Welcome to your DVD collection. Please enter a selection.\n";
do
{ //displays menu till user enters EXIT(5)
switch (displayMenu()) //switch statement pg 202
{
//DISPLAY ALL MOVIES IN THE LIST
case 1:
if (!list.empty()) //If there is anything in the list vector, it will show it
{
selectionSort(list); //make the vector alphabetical **not working**
cout << "Enter the movie number to view more details." << endl;
for (int i = 0; i < static_cast<int>(list.size()); i++)
{
cout << i + 1 << ". " << list[i].getTitle() << endl;
}
cin >> selection;
cout << endl;
while (selection <1 || selection > static_cast<int>(list.size()))
{
cout << "Invalid selection. Enter the number associated with the movie.\n";
cin >> selection;
}
movie1.displayContents(list[selection - 1]);
}
else
{
cout << "There are no movies in this collection.\n\n"; //If nothing is in the vector called list, it will tell the user that it is empty
}
break;
//ADD A MOVIE TO THE LIST
case 2:
do {
OVER = false;
++c; //counter with how many movies
DVD newMovie; //create a new object
addDVD(newMovie); //add the information into myMovie1
list.push_back(newMovie); //make a new spot for the object
