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 2017-07-18 11:51 GMT+03:00 Marcus Müller <muel...@kit.edu>: > Hi Ali, > > I think this should also work, shouldn't it? > > no, that's why I explained what you need to do (use makev). > > Does this part need to be changed since I am working with the vectors? > > No, not really.
