Hi,
I dont have any background about C++. So I could not generate the
std::vector<int> with the desired content and could not fınd anything on
the internet.
const std::vector<int> inputs[] = {4000,4000,4000,4000,4000,4000,4000,4000};
does not work. I am getting the following error:
"conversion from 'int' to non-scalar type 'std::vector<int>' requested"
Best,
Ali
