How to convert a std::array to a std::vector?

Question

I need to convert a std::array to a std::vector , but I could not find anyway to do it quickly. Here is the sample code:

 std::array<char,10> myData={0,1,2,3,4,5,6,7,8,9};

Now I need to create a vector such as:

std::vector<char> myvector;

and initialize it with the array values.

What is the fastest way to do this?

Answer 1

You can use the constructor of std::vector taking iterators.

Constructs the container with the contents of the range [first, last).

eg

std::array<char,10> myData = {0,1,2,3,4,5,6,7,8,9};
std::vector<char> myvector(myData.begin(), myData.end());

Answer 2

std::vector<char> myvector { myData.begin(), myData.end() };

Answer 3

I'd use the range constructor of vector - looking like myvector(myData.begin(), myData.end())

Answer 4

只是为了多样性：

std::vector<char> myvector(std::begin(myData), std::end(myData);
