At the beginning: sum = 0 i = 4 First iteration: sum += i --> sum = 0 + 4 --> sum = 4 i++ --> i = 4 + 1 --> i = 5 Second iteration: sum += i --> sum = 4 + 5 --> sum = 9 i++ --> i = 5 + 1 --> i = 6 Third iteration: i == 6 is true, so continue is triggered, skipping the rest of the interation, so i is not added to the sum i++ --> i = 6 + 1 --> i = 7 Fourth iteration: sum += i --> sum = 9 + 7 --> sum = 16 i++ --> i = 7 + 1 --> i = 8 Loop ends: i<8 is false, so the loop ends sum = 16
