In C++ Land we do it like this:

struct StupidSolution {
   int i;
   struct StupidSolution *self;
   StupidSolution(int num) : i(num), self(this) { }
};

But maybe you really wanted to do a tree:

struct TreeNode {
   int i;
   struct TreeNode *parent, *left, *right;
   TreeNode(int num, TreeNode *par=NULL) : i(num), parent(par), left(0),
right(0) { }
};

And if you doing it old fashioned in C:

struct StupidSolution {
   int i;
   struct StupidSolution *self;
};

struct StupidSolution *sol=(struct StupidSolution)malloc(sizeof(struct
StupidSolution));
sol->i=3;
sol->self=sol;
