Question

Like this question already asked, I’d like to initialize a container using STL where the elements are hard-coded in the cleanest manner possible. In this case, the elements are a doubly nested container:

set<vector<int> > A;

And I’d like (for example) to put the following values in:

A = [[0,0,1],[0,1,0],[1,0,0],[0,0,0]];

C++0x fine, using g++ 4.4.1. STL is preferable as I don’t use Boost for any other parts of the code (though I wouldn’t mind an example with it!).

Answer 1

This does use g++ 4.4.1, with -std=c++0x

#include <set>
#include <vector>

using namespace std;

int main()
{
    set<vector<int>> A = {{0,0,1},{0,1,0},{1,0,0},{0,0,0}};

}
