}

These are the errors I've been getting and I've looked everywhere for an answer to what the error means and how to fix it.

auto RoutePlanner::CalculateHValue (RouteModel::Node *node) {

return node->distance(*end_node);

}

------------

void RoutePlanner::AddNeighbors (RouteModel::Node *current_node) {

current_node->FindNeighbors();

float n;

for (n : current_node-> neighbors){

n->parent=current_node;

n->h_value= CalculateHValue(n);

n->g_value= current_node->g_value + current_node ->distance(*n);

open_list.push_back(n);

n->visited = true;

}

}

---------

RouteModel::Node *RoutePlanner::NextNode() {

std::sort(open_list.begin(),open_list.end();

[](const float &first_n, float &second_n)

{

return first_n->h_value + first_n->g_value < second_n->h_value + second_n->g_value;

}

);

RouteModel::Node *Nodef = *(open_list.begin());

return Nodef;

----------------

and the last one is at the end of the code but it lines up with another { so i don't understand.

If anyone can help please let me know!! Thanks!!!
