Courses Plus Student 6,664 PointsError in quiz "Arrays"
In the 3 question part quiz, one of the questions asks "what will happen when we run this code" type of thing. The first array is called "primes" and the second one tries to call an array called "a." This is confusing.

Treehouse TeacherHi! Well let's take a closer look at that question:
//What will happen when the following code runs.
int[] primes = {1, 3, 5, 7, 9};
int fifthPrime = a[5];
And you're correct, that à should be primes, I believe. But of the given choices even if we made that change, there would only be one correct answer and that's a[5] will throw System.IndexOutOfRangeException. The logic here being that it will be out of bounds for the size of the array given. Because arrays are 0 indexed in C# (meaning they start with an index of 0) it means that the 9 is in the space primes[4]. There is no primes[5]. Hope this helps!
