will be called before it is time to process the data, I need a dynamic storage structure, so I chose a std::vector. I don't want to have to do the standard loop to push_back all the values individually, it would be nice if I could just copy it all using something similar to ...
the first vector? If you do a shallow copy as in David's example using a simple assignment, then the pointers in both vectors will point to the exact same structs. If you later alter the contents of one of those structs in one of the vectors, the change will be reflected ...
If you want to copy the vector back into the array, you'll need to size it down: myvec.resize( MAX_SIZE); 1. Or you could limit the number of elements you copy back: copy( myvec.begin(), myvec.begin()+MAX_SIZE, myarr); ...
