How to initialize vector <char> string?

Question

Is it possible to initialize vector<char> from a string in a single line of code?
I do this:

 vector<char> vec; string str = "To travel you need a wish and your passport"; for (auto it : str) { vec.push_back(it); }

But I would like to know a more elegant way.

 string str = "To travel you need a wish and your passport"; vector<char> vec(str.begin(),str.end());

Good for you?

Can also

 vector<char> vec(begin(str),end(str));

or better yet

 vector<char> vec(cbegin(str),cend(str));

These options ( begin/end and cbegin/cend , but not str.begin() and str.end() ) will work for the proposed @Abyx

 constexpr char str[] = "...";

but in this case one should not forget that the terminating null character, which also appears in the vector, also enters str .

@Abyx Here you can resort to vector<char> v(begin(str),end(str));
- just take into account that the zero terminating symbol will be added to the vector ...
@Abyx You see, I am not sure that it is necessary to indicate this in the answer.
I will explain myself :) If you work with string , then it is clear what you mean by string .
If with a C-style string, then this terminating null character can be significant, and I wouldn't throw it away just like that.
