the program

----------------------------------------------

#include <iostream>
#include <string>

using namespace std;

struct Node
{
string name;
Node *NEXT;
Node (const string &s, Node * n = NULL): name
(s), NEXT (n)
{
}
};

class List
{
private:
Node *START,
*CURRENT,
*PRECEDE;
public:
List()
{
START = CURRENT=PRECEDE=NULL;
}
~List()
{
destroy();
}
void addNode(const string &s)
{
if (START == NULL || s <==START->name)
{
START = new Node(s, START);
return;
}
Node *prev, *curr;
for (prev = curr = START; curr !=NULL && s >
curr->INFO; prev = curr, curr = curr->NEXT)
{
}
Node *n = new Node (s, curr);
prev->NEXT = n;
}
void destroy
{
while(START!= NULL)
{
CURRENT = START;
START = START->NEXT;
delete CURRENT;
}
START = PRECEDE = CURRENT = NULL;
}
};

int main()
{
List obj;
String s;
getline(cin, s);
obj.addNode(s);
}
