I'm trying to declare two structs with the same structure as a below.

struct pair {
    unsigned int r1;
    unsigned int r2;
    unsigned int diff;
};

struct srm {
    struct pair *pairs;
    struct pair *ordered_pairs;
};

And it generate the error 'std::pair': class template has already been declared as a non-class template.

Please help me, why it occurs? (I'm using vc12 (visual studio 2015))

Rename pair and don't use `using namespace std`. – zdf Oct 23 '17 at 02:41
[OT]: for `struct srm`, you may get rid of `struct` in `struct pair`. – Jarod42 Oct 23 '17 at 08:20
Thanks guys. It works well – Suho Cho Oct 25 '17 at 02:33
