writing a struct to file

struct employee
{
char name[30];
char hiredate[10];
float salary;
};


employee empl;

--------------------------------------------------------------------------------

1) fwrite(&empl, sizeof(struct employee), 1, fptr); sizeof type

2) fwrite(&empl, sizeof(empl), 1, fptr); sizeof variable


Considering that name will be variable length,
is there going to be a difference which fwrite i use ?

Name is not variable length. Name is 30 characters long.

Code:

---

printf("sizeof(struct employee) = %d\n", sizeof(struct employee));
printf("sizeof(empl) = %d\n", sizeof(empl));

I thought printing to a file was the same as the screen with regards to strings, it prints everything upter the \0 char, in which case 30 characters (29 to be exact) is the max.

>2) fwrite(&empl, sizeof(empl), 1, fptr); sizeof variable
Both are equivalent

Thank you everyone.....
