How to Shuffle an Array in C++ ?

Answer

In C++, you can shuffle an array using the Fisher-Yates shuffle algorithm.

✐ Examples

1 Shuffle Array of Integers

In this example,

We have an array named intArray containing integers.
We apply the Fisher-Yates shuffle algorithm to intArray.
We print the shuffled array to demonstrate the shuffling.

C++ Program

#include <iostream>
#include <algorithm>
#include <random>
#include <chrono>
int main() {
    int intArray[] = {1, 2, 3, 4, 5};
    int n = sizeof(intArray) / sizeof(int);
    unsigned seed = std::chrono::system_clock::now().time_since_epoch().count();
    std::shuffle(intArray, intArray + n, std::default_random_engine(seed));
    std::cout << "Shuffled Array: ";
    for (int i = 0; i < n; i++) {
        std::cout << intArray[i] << " ";
    }
    return 0;
}

Output

Shuffled Array: 4 2 1 5 3

2 Shuffle Array of Strings

In this example,

We have an array named strArray containing strings.
We apply the Fisher-Yates shuffle algorithm to strArray.
We print the shuffled array to demonstrate the shuffling.

C++ Program

#include <iostream>
#include <algorithm>
#include <random>
#include <chrono>
int main() {
    std::string strArray[] = {"apple", "banana", "cherry"};
    int n = sizeof(strArray) / sizeof(strArray[0]);
    unsigned seed = std::chrono::system_clock::now().time_since_epoch().count();
    std::shuffle(strArray, strArray + n, std::default_random_engine(seed));
    std::cout << "Shuffled Array: ";
    for (int i = 0; i < n; i++) {
        std::cout << strArray[i] << " ";
    }
    return 0;
}

Output

Shuffled Array: banana cherry apple
