Problem with simple C programming

Hi, I am having programming issues with C. I have not used C in quite a long time, and I am trying to refresh my practice of C for I need to use it for work. The program that I am having compiling issues with makes use of derived data type and structure. It is very simple, and taken directly from a textbook (see code at the end of post), however, I am getting the following compiling errors:

test.c:4: error: expected ‘)’ before ‘.’ token
test.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘.’ token
test.c:6: error: expected declaration specifiers or ‘...’ before string constant
test.c:6: error: expected declaration specifiers or ‘...’ before ‘student_1’
test.c:6: error: expected declaration specifiers or ‘...’ before ‘student_1’
test.c:6: warning: data definition has no type or storage class
test.c:6: error: conflicting types for ‘printf’
test.c:6: note: a parameter list with an ellipsis can’t match an empty parameter name list declaration


I use gcc compiler.
Any idea what is wrong with my code??
Thanks for any help you can provide.

Sincerely,

Yann


CODE:
(header file)

Code:

#include <stdio.h>
#include <stdlib.h>

typedef struct {
	char name[20];
	int age;
	int course_code;
	int course_year;
	long int student_id;
} Student;

(main file)

Code:

#include "header.h"

Student student_1;
strcpy(student_1.name, "Smith, Bert");
student_1.age = 17;
printf("student name %s, age %d ", student_1.name, student_1.age);

Perhaps you'd like to put your actual code inside a function (say main() or some such).

That was easy!
Thanks for the help.
