Solution

Can you correct the clear method

void Ordered_list::clear(){

//delete all node
while(list!=NULL){

node * temp = list;
   list = list->next;    // Move list pointer forward and then delete temp
   delete temp;

}

}


Let me know if there is any concern.

You are not freeing the memory in clear method.
