Subject: Re: [Boost-users] boost.pp : generate a const size_t array
initializer
2009/8/12 Hicham Mouline
Hello,
I have
const size_t MaxNumber = 16;
Can I generate this:
const size_t elts[MaxNumber] = {0, 1, ..., 15};
with Boost.PP?
I suppose I need to #define MaxNumber for PP?
----------------------------------------------------------------------------

#include <iostream>
#include <iterator>
#include
#define N 16
int main() {
const int elts[] = { BOOST_PP_ENUM_PARAMS(N, BOOST_PP_EMPTY()) };
std::copy(elts, elts + N, std::ostream_iterator<int>(std::cout, "\n"));
}

Thanks very much.
How about generating
const int elts[] = { other_array[0], .... other_array[N-1] };
Basically I wished to initialize at compile time 1 const array based on
another,
I don't see any metaprogramming that allows this.
Regards,
