Loosing one node in my program

[Bopaki]

Write your question here.
When I run my program, the node with info=30 gets lost. Please help

  Put the code you need help with here.
#include <iostream>
using namespace std;

int main() {
using namespace std; 	
	struct nodeType
	{
		int info;
		nodeType *link;
	} ;
typedef nodeType *nodePtr;

	nodePtr ptr, list;
	list = new nodeType;
	list->info = 20;
	ptr = new nodeType;
	ptr ->info = 28;
	ptr->link = NULL;
	list->link = ptr;
	ptr = new nodeType;
	ptr->info = 30;
	ptr->link = list;
        list = ptr;
	ptr = new nodeType;
	ptr->info = 42;
	ptr->link = list->link;
	list->link = ptr;
	while(ptr != NULL)
	{
		cout << ptr->info << endl;
		ptr = ptr->link;
		  }  	
}
