Trouble with structures

[valmaral]

Hello everyone I was having some trouble with my code in which I keep getting errors (in bold) that say error: no match for 'operator[]' in 'employee[i]'. I've looked on the forums and have found some solved problems yet somehow I can get mine to work. I just wanted to know how I can fix these issues. Thanks.

The [] operator is usually used with arrays, but your code isn't using any arrays.
It looks like you should be using arrays for several things though.
Assuming you wrote the code you've posted, why did you write lines 6 and 7?

const int NAMELEN = 65;
const int SIZE = 20;

What is the planned usage for these constants?

[valmaral]

actually yes I'm using arrays, it is supposed to be done as an array of structures. I wrote my code based on examples from a textbook though obviously it's not written correctly. The two constants are supposed to represent the maximum characters allowed for a name (NAMELEN) and the maximum amount of employees I can add (SIZE). I assume then I should change the struct to;

 struct Payroll
{
       char name[];
       double rate [];
       double hours[];
}

and add the [] at the end of each "employee" in my function calls?

[D80DSL3A]

I think only name would be an array in the structure:

struct Payroll
{
       char name[NAMELEN];
       double rate;
       double hours;
}

Then declare an array of Payoll objects in main():

//Payroll employee;// just one?
Payroll employee[SIZE];// array of 20 

Place the [] after Payroll in each function header. Example:
void printAllPaychecks(Payroll[] employee, int count)

It compiled and worked great! Thanks for all your help.
