3/09/2013 · I'm trying to avoid adopting bad habits as I learn to program in C++. I've read that reinterpret_cast is best avoided because it turns one type directly into another, which may cause unexpected results, especially when compiling and running the program on a system with a different architecture that might internally store the affected types...
You can avoid that with a bit of pointer magic: you would still have an array of pointers, but you can set them to point to the right places in the original data, so you don't have to copy it. Something like this:

  • The following implicit conversions are classified as integral promotions: signed char or signed short can be converted to int ; unsigned char , char8_t (since C++20) or unsigned short can be converted to int if it can hold its entire value range, and unsigned int otherwise;
  • 23/12/2005 · The C++ committee wanted enumerations to be isomorphic to the integers, and given the plethora of implicit conversions (especially widening) possible in C++, your code must therefore work.
