Hi @A_Huang, Thanks for reaching out to us.
The sum1 variable used in the program gives a value of 16 because there is a break statement that says
if(i + 5 >= 20){ break; }, which means the loop will break when the value of ‘i’ is greater than or equal to 15.
In for loop value of ‘i’ starts from 0 as shown in the code for(int i = 0; i <= 20; i++) so from 0-15, the total values become 16 because we have to include 0 as well.

Hope it will clear your confusion, Happy Learning :slight_smile:
