Im not sure about this, its my first actual functioning and cool project i made yeah its not really a big project, but its a start, well here it is:

// Online C++ compiler to run C++ program online
#include <iostream>
#include <string>
int main() {
    int arr[9] = {0, 0, 0, 0, 0, 0, 0, 0, 0};
    while (true){  
        for(int i = 0; i < 9; i++){
            std::cout << arr[i] << " \n";
        }
        
        int choice;
        int temp;
        std::cout << "choose which to turn on (1-9): ";
        std::cin >> choice;
        
        switch (choice){
            case 1:
                arr[0] = temp;
                arr[0] = 1;
                break;
            case 2:
                arr[1] = temp;
                arr[1] = 1;
                break;
            case 3:
                arr[2] = temp;
                arr[2] = 1;
                break;
            case 4:
                arr[3] = temp;
                arr[3] = 1;
                break;
            case 5:
                arr[4] = temp;
                arr[4] = 1;
                break;
            case 6:
                arr[5] = temp;
                arr[5] = 1;
                break;
            case 7:
                arr[6] = temp;
                arr[6] = 1;
                break;
            case 8:
                arr[7] = temp;
                arr[7] = 1;
                break;
            case 9:
                arr[8] = temp;
                arr[8] = 1;
                break;
        }
    }
}

code is messy i guess but its nice to see that it works, adding switching off functions soon though.

could make the code 100x easier but its too much brain usage for my knowledge level

What does temp do? 😄

[obsidian wing]

first of all, it seems like you aren't using temp, you are just assigning it without first initializing it, and also it's assignments are useless as you always do

arr[..] = temp;
arr[..] = ..;

overwriting arr[..] with another value.

#include <array>
#include <iostream>
#include <string>

int main() {
    std::array<int, 9> arr = {};

    while (true) {
        for (auto i : arr) {
            std::cout << i << " \n";
        }

        int choice;
        std::cout << "choose which to turn on (1-9): ";
        std::cin >> choice;

        arr[choice - 1] = 1;
    }
}

:p
