Theoretically, something like this should suffice: https://code.sololearn.com/cD9KN7vIbsH5/?ref=app But there is no point in speculating what might be an issue in your particular code, so you should link it here.

i didn't mean that array type,i meant the array with []

i dont want them to reconstruct because the values of the current class will reset

It doesn't matter whether you use std::array or a plain array, it should be the same. You could substitute the latter for std::array in my code and it would still work, since std::array only encapsulates a plain array. Obviously the container value will not yield 6 in your code, you never assign that value to the constructed object in your move constructor. It is important to realize that a move constructor works a lot like a copy constructor, except that you operate under the assumption that the original object doesn't need to be preserved. If anything, you would have to write: foo( foo&& other ) : val{ other.val } { cout << "&&constructor\n"; } And yes, it is quite hard to understand you if you give such little information regarding your problem ("got error" - What error? What error message? Where is the code?) and fractured explanations on top of that.
