    Question 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.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
