How do I initialize vector/array using an enum?

One way to solve this would be adding a value to the enum that is always the last one. Then you could fill the vector by looping up to the value. Something like this:

enum VALUES{

    VALUES_FIRST = 0,

    VALUES_SECOND,

    VALUES_END
};

std::vector<VALUES> Allvalues;

for(int i = 0; i < VALUES_END; i++){
    Allvalues.push_back(static_cast<VALUES>(i));
}

Would fill the vector with all the values in the enum (not including the last marker value) as long as you don't put anything after VALUES_END.

So if you want to generate a range from 1 to 32 you can use generate to do that, combined with a lambda.

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

int main() {
    vector<int> v(32);
    int n=0;
    std::generate(v.begin(), v.end(), [&]{ return ++n; }); 

    //to display the results
    for (auto& it: v){
        cout<<it<<" ";
    }
    return 0;
}

Output: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

Hope that helps
