Help with Structures!

I am new to the world of structures and pointers, and was trying to use a modified version of the program example given in the structures tutorial. Every time I try to run it, it crashes. Any advice?

Code:

#include <iostream>

using namespace std;

struct database
{
    int id_number;
    int age;
    float salary;
};

int main()
{
    database employee;
    database *ptr,*ptr1,*ptr2;

    employee.age=28;
    employee.id_number=1;
    employee.salary=12000.21;

    cout<<ptr->age;
    cout<<ptr1->id_number;
    cout<<ptr2->salary;

    cin.get();
}

You appear to have forgotten to initialise ptr, ptr1 and ptr2. You presumably want then to point to employee.

Oh! I see...stupid mistake on my part. Thank you very much for your help
