Explanation:
1. Card Structure:
- Defines a `Card` structure to represent a single card.
- Includes `name` and `type` attributes, but you can add more attributes as needed (attack, defense, etc.)
2. shuffleDeck Function:
- Takes a `vector - Implements the Fisher-Yates shuffle algorithm for efficient randomization:
- Iterates through the deck from the end to the beginning.
- For each element `i`, it generates a random index `j` within the range `[0, i]`.
- Swaps the elements at indices `i` and `j`.
- Returns the shuffled deck.
3. drawCard Function:
- Takes a `vector - Checks if the deck is empty. If so, prints an error message and returns a dummy card.
- If the deck is not empty, it retrieves the last card (top of the deck) using `deck.back()`.
- Removes the last card from the deck using `deck.pop_back()`.
- Returns the drawn card.
4. main Function:
- Creates a `vector - You need to add code here to populate the `deck` with actual card data.
- Calls `shuffleDeck()` to shuffle the deck.
- Calls `drawCard()` to draw a card from the shuffled deck.
- Prints the name of the drawn card.
To use this code:
1. Replace the comment `// ... (Add cards to the deck using a loop or manually)` in `main()` with code to initialize the deck with your specific card data. For example:
```cpp
std::vector {"Monster A", "Monster"},
{"Monster B", "Monster"},
{"Spell Card", "Spell"},
// ... add more cards
};
```
2. Compile and run the code. It will shuffle the deck and then draw a random card, printing its name.
Remember:
- This code provides a basic framework for shuffling cards. You can customize it by adding more attributes to the `Card` structure, modifying the `shuffleDeck` function (if you want to use a different shuffling algorithm), and extending the `main` function with more gameplay logic.
