Trying to stick randomly generated numbers into an array

Question

I'm working on a project currently that involves taking randomly generated numbers, putting them into an array, then using that array throughout the entire program. It's basically supposed to be a number version of wordle. What I'm stuck on right now it trying to make the function to array connection work, and I don't know what I'm doing wrong.

I'm in a beginner course for programming, so I'm probably making a lot of dumb mistakes. The purpose of the function is to generate 5 random numbers between 0 and 9. The I'm supposed to take those numbers and stick then into an array. Then the array needs to be saved so it can be used for a game.

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

using namespace std;
//using std::array;

    int getRandomDigit() {
        std::random_device randomSource;
        unsigned seed = std::chrono::system_clock::now().time_since_epoch().count();
        std::default_random_engine engine(seed);
        std::uniform_int_distribution<int> uniformDist(0,9);

        //for (int i = 0; i < 5; i++) {
        int digits[5] = {getRandomDigit(),getRandomDigit(),getRandomDigit(),getRandomDigit(),getRandomDigit()};

        return digits[5];
    }

    //for (int i = 0; i < 5; i++) {
    //int randArray[5] = {getRandomDigit(),getRandomDigit(),getRandomDigit(),getRandomDigit(),getRandomDigit()};


int main()
{
    //for (int i = 0; i < 5; i++) {
    //int randArray[5] = {getRandomDigit(),getRandomDigit(),getRandomDigit(),getRandomDigit(),getRandomDigit()};
    //}
    cout << digits[1] <<endl;

    return 0;
}

This is what I have so far. I compile it, and it gives me an error of "'digits' was not declared in this scope". I'm honestly very lost on how to make this work. The random number generator was given to us by our instructor

Answer 1

Your compilation error "'digits' was not declared in this scope" is because you are using digits in your main function without declaring it first. You only have it declared in getRandomDigit(). Declare your array in main() instead and set it to values that are returned from getRandomDigit(). Additionally, you can not return an array in C++ directly. Focus on returning a single int from the getRandomDigit() function and populating your array in main().
