...dard smart pointers, the biggest reason is probably the lack of a standard C++ Application Binary Interface (ABI).
If you’re writing a header-only library, you can pass around smart pointers and standard containers to your heart’s content. Their source is available to your library at compile ti...
What are the dangers when creating a thread with a stack size of 50x the default?
...Consider the following code:
float[] someArray = new float[100]
someArray[200] = 10.0;
You expect an out of bound exception and this completely makes sense because you are trying to access element 200 but the maximum allowed value is 99. If you go to the stackalloc route then there will be no obj...
