Given:

1. int main(int argc, char *argv[ ])

2. {

3. int array[ ]={100,200,300,400,500,600,700,800,900,1100};

4. int *p,p1;

5. p=array; // p = &array[0]

6. p1=*p+100;

7. printf("%d ",*p);

8. printf("%d ",*(p+3));

9. printf("%f ", *(p+3));

10. printf("%x ", *(p+3));

11. printf("%x ",*(p-5/2));

12. printf("%d ",p1+50);

13. return 0;

14. }

What are the differences between line 8, line 9, line 10?
