I need to build destructor class function for this but i dont know how.

#include <iostream>
#include <string>
using namespace std;

class node {
public:
	string name;
	node *next;
	node(string input) {name = input; next = NULL;};
    
};

for string class it was

~Stirng();
Stirng::String(){
delete [] ptr;
}

but for this i dont know

Firstly, the destructor you posted doesn't have ~, though that might have been a typo.

Do you need to delete next ? I don't see where the problem is..

Revise the example so that it destroys nodes upon exit. this is what i must do.

Well, then write a destructor and put delete next; in it. If you don't know how to write one, see http://www.cplusplus.com/doc/tutorial/classes/ (around middle)

Pretty much yes, just be sure you don't delete memory thats not yours (NULL/Uninitialized)
