compilation is fine but there is some problem in linking. But i am not able to track the error

#include <iostream>
using namespace std;
class Node
{
	public:
		int data;
		Node *next;

		Node(int val)
		{
			data = val;
			next = NULL;
		}

};

Node* reverse(Node* head)
{
	if (head == NULL)
	{
		return NULL;
	}
	Node *current = head;
	Node *link = NULL, *tmp = NULL;
	while (current != NULL)
	{
       link = current->next->next;

       if(current->next!=NULL)
       {
       	tmp->data = current->data;
       	current->next->data = current->data;
       	current->data = tmp->data;

       }
         current = link;
	}
      return head;

}

void cleanlist(Node*head)
{
	while(head!= NULL)
	{
		Node*temp = head;
	    head=head->next;
	    delete temp; 
	}
}

int Main()
{
	int n;
	Node* result = NULL, *first = NULL, *last = NULL;
	cout<<"\n Enter the number of elements in linklist:";
	cin>>n;
	cout<<"\n Enter the elements in linklist";
	for (int i=0; i<n;i++)
	{
		int val;
		cin>>val;

		Node* node = new Node(val);
		if (first = NULL)
		{
			first = node;
			last = node;
		}
		else
		{
			last->next = node;
			last = node;
		}

	}

	result = reverse(first);

	Node * temp;
	temp = result;

	cout<<"\n Reversed linklist is:";
	while (temp!=NULL)
	{
	     cout<<temp->data<<" ";
	     temp = temp->next;
	}

	cleanlist(first);

	return 0;
}

What is the linker error?

Line 52: main is misspelled. main() MUST be lower case.
