Declaring Variables for Arrays~ Newbie Question

I just wanted to know if these are appropriate declarations
digits is an array of 10 integers = int digits [10]
rates is an array of 6 floats = float rates [10]

digits is good, rates isn't.

Code:

---

int digits[10];
double rates[6];

---

But make sure you know 10 and 6 is how many, not the size.
And that start indexing at 0.
So you have digits[0] through digits[9].

Code:

---

//declared earlier

digits[0] = 555; //First value in array gets 555
digits[9] = 323; //Last value in array gets 323
rates[4] = 99.99; // 5th value in rates array gets 99.99
