Why no change in emplace_back and push_back

Question

Hi

Trying to store string into vector.

Tried two ways 1. Push_back and 2.emplace_back

I could observe two allocations on heap for both approaches.

Should emplace be more efficient than push here also ? Or am i missing something ?

Ketan Lalcheta maybe this might be helpful .. I would say emplace_back would be your best approach given this code however there may be times whereas yes push_back would qualify .. It really depends on what you intend to do.
