C++11 emplace_back on vector?

Question

Consider the following program:

#include 
#include 

using namespace std;

struct T
{
    int a;
    double b;
    string c;
};

         


        

Answer 1

Of course, this is not an answer, but it shows an interesting feature of tuples:

#include 
#include 
#include 

using namespace std;

using T = tuple <
    int,
    double,
    string
>;

vector V;

int main()
{
    V.emplace_back(42, 3.14, "foo");
}
