Answer 1

If you have the same problem in 2019, You are using an older initialization style for unassigned pointers. After 2014 August 14 the C++ 11 released. The compiler you are using is probably following the C++11 standard.

You can just replace 0/NULL with nullptr

Modern C++ offers nullptr as a universal null pointer. You should use that instead of 0 || NULL because there are some obscure machines that have things like signed pointers where a null pointer is actually something like -1 rather than 0.
