Array To Vector Conversion

[D. Susman]

Hi,

I am wondering if there is a short way (i.e. one liner) to convert an
array into a list, vector etc. in c++.

Thanks.

STL Containers all have constructor

Container(Iterator first, Iterator last, extra default parameters)

take std::vector for example,
you can write

int arr[] = {1, 2, 3, 4, 5};
std::vector<int> V(arr, arr + sizeof(arr)/sizeof(int));

Assuming
- your vector is named a
- the array is named a
- the size of the array is s
, one option would be:

v.assign(a, a + s);

Hope this helps.

Cheers,

You can also use boost::array, which provides STL iterator semantics to
a plain old C array.
