C++ Question

This is a musical program problem

I have a struct like the following:

struct a_triplet
{
int first;
int second;
int third;
}triplet;

and I have about 297 individual notes, each with an associated pitch....stored in an array...something like

pitch_array[note_counter];

My problem is that I want to fill the triplet struct described above, with notes 1, 2, and 3 ....then fill a second triplet struct with notes 4, 5, 6... and a third with 7, 8, 9...and so on..

I was thinking about doing this with an array of structs...but how exactly do I go about pumping in three notes, then skipping 3 and pushing another three into the next struct?

how bout something like :

int TOTALNOTES = 297; //or what ever your totalnotes will be

triplet triplet_array[TOTALNOTES / 3] ; // since 3 notes per triplet

then the for loop :

for (int i = 0; i < TOTALNOTES; i+=3)
{
// the first element, i.e. num 1,4,7 etc
triplet_array[i/3].first = pitch_array;
// the second i.e. num 2,5,8 etc
triplet_array[i/3].second = pitch_array[i+1];
// the third i.e. num 3,6,9 etc
triplet_array[i/3].first = pitch_array[i+2];
}

its a bit rough but you should get the jist of it
