vector fast copy
So without further delay, here are the 6 quick recipes to optimize your usage of C++ 11 vectors. #1 Avoid unnecessary reallocate and copy cycles ...,Check out the insert() and copy() function. There are examples here: http://programmingexamples.net/index.php?title=CPP/STL/Vector. David. , In conclusion, std::copy is less expressive, might do the wrong thing and isn't even faster. So there isn't really any reason to use it here., I think what you are looking for are move semantics. Vector<A> vA1(100); // vA1 is allocated A[100] Vector<A> vA2 = std::move(vA1); // vA2 ..., This answer is not specific to the msvc100. If you use the copy constructor like in std::vector<uint8_t> newVect(otherVect);. the otherVect's ..., Your second example does not work if you send the argument by reference. Did you mean void copyVecFast(vec<int> original) // no reference ..., I donot know which one of them is faster or more convenient but I dont know any better way to copy a vector conditionally ? share.
