<pre>#include "iostream"
#include <valarray>
int main() {
int input[] = { 0, 1, 2, 3, 4, 5, 6 };
std::valarray<int> filled(input, 7);
size_t indexes[] = { 1, 3, 4, 6 };
std::valarray<size_t> index(indexes, 4);
size_t indexes2[] = { 1, 2, 3, 4 };
std::valarray<size_t> index2(indexes2, 4);
const std::indirect_array<int> result = filled[index];
const std::indirect_array<int> result2 = filled[index2];
result = result2;
std::valarray<int> temp(result);
for (int i = 0; i < temp.size(); i++)
std::cout << temp[i] << " ";
}
using clang, this will print:
1 2 2 2
using msvc or gcc, this will print:
1 2 3 4</pre>
