What does "suitable" mean ? With many embedded CPUs alignment is forced to prevent runtime errors. With an X86 any alignment is allowed but performance is different Of course for Integers and Pointers Dword alignment (or QWord for 64 Bit systems) is appropriate (and supposedly provided by malloc. But with Vectors (and long Reals) more strict alignment might be faster. malloc() does not handle this. The C library provides calloc() for this purpose, but I don't know how this exactly works. I suppose it is implementation-depending.
