I'm just learning Objective C and writing a program to aid people in learning to play the guitar. I wanted to create a 2D array containing (almost) all the notes on a guitar neck. Since there are six strings on the guitar and twelve notes in an octave, I created a 6 x 12 array. EDIT: solution is now at bottom
The intention here is for the array to be read as (string),(fret number).
int strings[6][12] = { { {0, 8},{0, 9},{0, 10},{0, 11} ,{0, 12} ,{0, 1}, {0, 2},{0, 3},{0, 4},{0, 5},{0, 6},{0, 7} }, { {1, 3},{1, 4},{1, 5},{1, 6},{1, 7},{1, 8,},{1, 9},{1, 10},{1, 11} ,{1, 12},{1, 1},{1, 2} }, { {2, 12},{2, 1},{2, 2},{2, 3},{2, 4},{2, 5},{2, 6},{2, 7},{2, 8},{2, 9},{2, 10},{2, 11} }, { {3, 6}, {3, 7} , {3, 8} , {3, 9} ,{3, 10} ,{3, 11} ,{3, 12} ,{3, 1} ,{3, 2} ,{3, 3} ,{3, 4} ,{3, 5} }, { REPLY 0 views 0 likes 0 shares Facebook Twitter Linked In WhatsApp
Moved from the question to an actual answer post:
Thanks to you cool people, I figured out the problem. In the event someone else has this problem, here is my solution. I came to realize that the problem was that I had two integers assigned in each array slot, effectively making the array a 3D array. Since the first number in each pair is just the string number, I went ahead and just got rid of it. No more warnings!** int strings[6][12] = {8, 9, 10, 11, 12, 1 ,2 ,3, 4, 5, 6, 7, // High e 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 1, 2, // B 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, //G 6, 7, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, // D 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, // A 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7 }; // E
