What is wrong with the following code fragment?

const int SIZE =5;
float scores[SIZE];
for(int i=0; i<=SIZE;i++)
{
cout << "Enter a score\n";
cin >> scores[i];
}

a. Array indexes start at 1 not 0
b. Arrays must be integers
c. Array indexes must be less than the size of the array
d. Should be cin >> scores[0];

c. Array indexes must be less than the size of the array
