vector< pair<aStruct*,int> > not possible?

Question

So I tried to make a vector which elements are pairs of a struct pointer and an int, and I'm beginning to think that this may be impossible..

Suppose I have the following struct:

struct node{
  string str;
  int size;
  node *child[3];
  node(string str1):str(str1){ size = 0;}
};

and a vector:

vector< pair<node*,int> > nodvector;

Then I tried to make a new node and put it in the vector, and apparently it's not working:

int main(){
   node* nod1 = new node("HELLO");
   node* nod2 = new node("WORLD");
   nodevector.push_back(pair<nod1,3>);
   delete nod1;
   delete nod2;
}

The compiler barks at me saying: nod1 cannot appear in a constant-expression error: template argument 1 is invalid error: type/value mismatch at argument 2 in template parameter list for template struct std::pair

Is this just something impossible? What could be an alternate solution to this? Your input will be so much appreciated!

Answer 1

nodevector.push_back(pair<node*,int>(nod1, 3));
