In this case, we can "loop around" the array declared above to find that the middle note of the triad is B. And the final note of the G major chord is D. Note that this "loop around" operation can be implemented in arrays using the mod (%) operator. If we tried to use the index in the code above for the second note of the G major chord (i + 4), we would generate an "out of bounds" error. The index of G is 10, and 10+ 4 = 14, which is greater than the index of the final array element ("G#" is at position 11). A similar problem would occur for the third note. I am happy to help, but try to resolve this problem out on your own. As a hint, using %12 in the subscript operator would probably be the most straightforward approach.

Extension of this assignment as an extra credit project (optional) If this program interests you or you have experience with music theory, you might enjoy extending this program to include seventh chords, suspended chords, inverted chords, etc. Or you might go in the "reverse" direction and determine the name of a chord based on notes input by a user.

{
string firstNote = notesArray[i];
string secondNote = notesArray[i + 4];
//determine thirdNote using the above information

As a less straightforward chord example, suppose that you choose the root note G. In this case, we can "loop around" the array declared above to find that the middle note of the triad is B. And the final note of the G major chord is D.
Note that this "loop around" operation can be implemented in arrays using the `mod (%)` operator. If we tried to use the index in the code above for the second note of the G major chord (i + 4), we would generate an "out of bounds" error. The index of G is 10, and 10 + 4 = 14, which is greater than the index of the final array element ("G#" is at position 11).

![In traditional Western music, we use the following 12 note names to refer to pitches/frequencies:
A, A#, B, C, C#, D, D#, E, F, F#, G, G#
(The # symbol is read as "sharp" - there is an alternative listing of notes that uses "flat" notes, but let's just use sharps for this assignment).
1) Declare a 1D array to hold these 12 notes.
2) Write code that loops through this array (could be named notesArray), prints the "major triads" (see below for definition) of all 12 notes, and stores their values as strings in a separate array (could be named triadsArray).
A major triad (chord) can be defined as the following three notes:
i) a "root note" - this can be chosen as any of the 12 notes listed above
ii) the note 4 positions above the root note
iii) the note 7 positions above the root note
As an example, suppose that you choose the root note C. In this case, the note 4 positions above C is E. And the third note of the triad is G.
Therefore the C major chord is given by the notes C, E, and G. (If the song "Kumbaya" is familiar to you, its first three notes/syllables (Kum-bah-yah) make up a major chord.)
There is more than one approach to writing the code that generates the chords, but you might start with something like the following:
```plaintext
string notesArray[] = {"A", "A#", ... "G#"};
string triadsArray[12]; //uninitialized - to be filled in with loop below
for (int i = 0; i < 12; i++)
{
string firstNote = notesArray[i];
string secondNote = notesArray[i + 4];
```
