i have some very simple algorithm to calculate percentage from items in array:

2.  //array of percents
3. float[] city={69.7, 75, 73.7, 78.9, 81.6, 77.6, 84.2, 77.6, 85.5, 84.2};
4. 
   
5. float cityComp=0; 
6. float cityFinal=0;
7. 
   
8. //sum of array
9. for (int i = 0; i<city.length; i++){ 
10.   cityComp+=city[i];
11. }
12. 
    
13. //percents from sum
14. cityFinal = cityComp/city.length; 
15. 
    
16. println(cityFinal);

My question is how can I apply this algorithm on another array without have to write new variables etc.

Thanks for any help ;)

2. int strokeFat = 25;
3. int numberOfCuts = 10;
4. int numberOfArcs = 9;
5. float cut = TWO_PI / numberOfCuts;
6. float dis = 70;
7. float[] rad = new float [numberOfCuts];
8. 
   
9. void setup() {
10.   println(cut);
11.   size(800,800);
12.   stroke(0);
13.   strokeCap (SQUARE);
14.   background(255);
15.   smooth();
16.   int cx=width/2;
17.   int cy=height/2;
18. 
    
19.   for (int i = 0; i<numberOfCuts; i++) {
20.     rad[i]=cut++;
21.     println(rad[i]);
22.   }
23. 
    
24.   for (int i = 0;i<numberOfArcs;i++) {
25.     arc (cx,cy,i*dis,i*dis,0,rad[i]);
26.     noFill();
27.     strokeWeight(strokeFat);
28.   }
29. }

I think there is many of things going wrong :) but main problem is, that I can´t make smaller cuts of arcs. Value of how much is arc open or close is get from TWO_PI / numberOfCuts variable called cut, which is than stored in array. I think this proceeding is not optimal.

Can anyone help pls? I will be thankful for any help.
