Does valarray have contiguous memory alignment?
arrays, c++, memory-alignment, stl
Solution
Assuming you're asking whether the memory managed by a valarray is guaranteed to be contiguous, then the answer is yes, at least if the object isn't `const` (C++03, §26.3.2.3/3 or C++11, §26.6.2.4/2):
The expression &a[i+j] == &a[i] + j evaluates as true for all size_t i and size_t j such that i+j is less than the length of the non-constant array a.
Problem
Does `valarray` have contiguous memory alignment? I want to pass a valarray to a function (from IPPS), which only takes pointers, by passing `&myValarray[0]`. But therefore I should be sure, that valarray's memory alignment is contiguous. Thanks!
