How to cheaply assign C-style array to std::vector?

Question

Currently I do the following:

// float *c_array = new float[1024];

void Foo::foo(float *c_array, size_t c_array_size) {
  //std::vector cpp_arr         


        

Answer 1

Currently, the std::vector interface does not possess the capacity to move from or swap with anything except another std::vector.
