Linked Lists Help

[norcal]

How do I modify this program to track the numbers guessed by the user using a linked list. So basically, i need to keep track if someone already guesses a number and then output if the user did.

#include<iostream>
#include<cstdlib>
#include<ctime>

using namespace std;

int main()
{
    srand(time(0));

    int number = rand()%100+1;
    int guess;

    cout << "Im thinking of a number between 1-100. Try to guess what it is: ";
    cin >> guess;

    while(guess!=number)
    {
        if(guess>number)
        {
            cout << "That's too high, guess again: ";
            cin >> guess;
        }
        if(guess<number)
        {
            cout << "That's too low, guess again: ";
            cin >> guess;
        }
    }

    if(guess==number)
    {
        cout << "That's right! It's " << number << endl;
    }

    return 0;
}

If you must supply your own linked list type, then the first step is probably designing a simple linked list interface separate from this code.
