(...) I should have written: 'array' (...) OK, undefined is not the same as zero, that makes sense (in a way). I looked up how to initialise an array and according to Dave Baum's NQC Guide "The initial values for an array's elements cannot be (...) (18 years ago, 14-May-07, to lugnet.robotics)

I've inserted some comments, not all are questions, some are simply 'thinking aloud'. (...) So by defining SIZE here I can easily change the size of the macro without having to alter anything else in the code. Nice! (...) Right you are, I should (...) (18 years ago, 13-May-07, to lugnet.robotics)

I've added my comments to the code you posted (they start with **). I've also added some indenting.: #define SIZE 3 int v[SIZE],i,sum,ave; // initialize the array and some other variables sum = 0; for (i=0;i<SIZE-1;i++) { //I think this means set (...) (18 years ago, 13-May-07, to lugnet.robotics)

(...) The line above is the line that cycles the array - each time through the loop it increments i and resets it to zero if it's >= SIZE (% is modulus operator). But I would agree with you about the v[i]=0 line - seems to me it would make the (...) (18 years ago, 12-May-07, to lugnet.robotics)

(...) This is indeed the main problem. As we originally defined a GBC it used soccer balls (at the time, Zamors hadn't yet even come out), so most GBC-standard modules not only use but take advantage of the fact that a LEGO soccer ball fits very (...) (18 years ago, 11-May-07, to lugnet.robotics)
