Thread: Understanding Struct

trying to compile this example to get a better understanding of structures... but i keep getting errors.

Code:

#include <stdio.h>

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

int main()
{
  database employee;  //There is now an employee variable that has modifiable 
                      // variables inside it.
  employee.age = 22;
  employee.id_number = 1;
  employee.salary = 12000.21;
}

any tips on better understanding this would be awesome. I'm trying to learn struct's!

Thanks

For better understanding (on our part), post the exact error messages next time. As for your problem:

Code:

struct database employee;

Add the word struct there. database on it's own is not a valid type. You could also do the following:

Code:

typedef struct database    database_t;

int main(void)
{
    database_t employee;
...
    return 0;
}

typedef makes database_t a synonym for struct database. Also, it's best to state that main explicitly takes no parameters, and, since you said it would return an int, you ought to make it do so, hence the return 0.
