C++ Random number generator from a specific array

Question

I want to be able to generate random numbers from a specific array that I will place. For example: I want to generate a random number from the array {2,6,4,8,5}. its just that there is no pattern in the array that I want to generate.

I was only able to search how to generate a random number from 1-100 using srand() from the video tutorial https://www.youtube.com/watch?v=P7kCXepUbZ0&list=PL9156F5253BE624A5&index=16 but I don't know how to specify the array that it will search from..

btw, my code is similar to this..

#include <iostream>
#include <cstring>
#include <cstdlib>
#include <ctime>

using namespace std;

int main(int argc, char*argv[])
{
    srand(time(0)); 

    int i =rand()%100+1;
    cout << i << endl; 
    return 0;
}

Here is a modern C++ way to do it:

#include <array>
#include <random>
#include <iostream>

auto main() -> int
{
    std::array<int, 10> random_numbers = { 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 };

    std::random_device random_device;
    std::mt19937 engine(random_device());
    std::uniform_int_distribution<int> distribution(0, random_numbers.size() - 1);

    const auto random_number = random_numbers[distribution(engine)];
}
