John:
U remember when I told u Saturday that a struct was declared as:
struct employee {
int clock;
float hours_worked;
float overtime;
float gross_pay;
}
struct employee emp;
1 thing u did here was 2 try 2 declare struct emp b4 u ever defined it.
Now, let's look at some of these errors:
void initData(emp, SIZE);
U do not define what emp or size is, e.g., u should declare the
employee struct b4 u do that, u also need to define to the function
what size is--remember, your computer failed telepathy 101.
So, declare your struct first, then say something like:
void initData(struct emp, int SIZE);
Remember, you've gotta tell your compiler *everything*--data types, etc.
Now, u say:
initData(clockNumber,wage,hoursWorked);
but when u declared the function, u said:
initdata(emp, size)
So you're contradicting yourself, & the compiler is telling u this.
Also, u never declared a function called GetHoursWorked.
