I'm trying to implement a Graph class with shared_ptr. I've declared my class as below.
class Graph
{
public:
Graph(int V);
Graph()=delete;
void AddEdge(int src, int dest);
void BFS(int s);
~Graph();
private:
int V;
std::shared_ptr<std::list<int>[]> adj;
};
When I try to initialize my adjList like below in the constructor, I'm getting a compilation error.
Graph::Graph(int V)
{
this->V = V;
adj = std::make_shared<std::list<int>[]>(new std::list<int>[V]);
}
Error:
/usr/include/c++/9/bits/shared_ptr.h:717:39: required from ‘std::shared_ptr<_Tp> std::make_shared(_Args&& ...) [with _Tp = std::__cxx11::list<int> []; _Args = {std::__cxx11::list<int, std::allocator<int> >*}]’
Graph.cpp:21:67: required from here
/usr/include/c++/9/ext/new_allocator.h:145:20: error: no matching function for call to ‘std::__cxx11::list<int>::list(std::__cxx11::list<int>*)’
What am I doing wrong ?
