Is vector not allowed ? (error: invalid use of ‘auto’)

Question

I have:

#include 
#include 

using namespace std;

int main()
{
   auto a = -SOME_CONST_MAX;
   vector myVec {a, a,          


        

Answer 1

I find Slava's solution really simple and elegant

vector myVec {a, a, a, a};

But just to show another way, you can use the variadic template function

template 
std::vector getVect (T const & t, Ts const & ... ts)
 { return { t, ts... } ; }

You can use auto again

auto myVec = getVect(a, a, a, a, a);
