A shuffling machine in C++ can be implemented using an array to represent the deck of cards and using the random number generator to shuffle the cards. Here is a sample code for a shuffling machine:
```
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
const int NUM_CARDS = 52;
class ShufflingMachine {
private:
int deck[NUM_CARDS];
int position;
public:
ShufflingMachine() {
for (int i = 0; i < NUM_CARDS; i++) {
deck[i] = i;
}
position = 0;
}
void shuffle() {
srand(time(NULL));
for (int i = 0; i < NUM_CARDS; i++) {
int j = rand() % NUM_CARDS;
swap(deck[i], deck[j]);
}
position = 0;
}
int dealCard() {
if (position >= NUM_CARDS) {
shuffle();
}
return deck[position++];
}
};
int main() {
ShufflingMachine shuffler;
shuffler.shuffle();
for (int i = 0; i < NUM_CARDS; i++) {
cout << shuffler.dealCard() << " ";
}
cout << endl;
return 0;
}
```
In this code, the `ShufflingMachine` class represents the shuffling machine. The `deck` array stores the deck of cards, and the `position` variable keeps track of the current position in the deck.
The `shuffle` method shuffles the deck by randomly swapping cards. It uses the `srand` function to seed the random number generator with the current time, and the `rand` function to generate random indices for swapping cards.
The `dealCard` method deals the next card from the deck. If the deck has been exhausted, it calls the `shuffle` method to shuffle the cards again.
In the `main` function, we create a `ShufflingMachine` object and shuffle the cards. Then we deal all the cards and print them out.
