loops

Question

What is the output of this code?
int result = 0;
for (int i = 0; i < 5; i++) {
if (i == 3) {
result += 10;
} else {
result += i;
}
}
System.out.println(result);

i did not get it someone explain it to me

Answer 1

Ahmed Hesham The output is 17.

Result is initially 0.

It keeps increasing in the for loop.
for(int i = 0; i < 5; i++){
result gets added to i after each iteration unless i has reached the iteration of 3, in that case add 10.
}

So in this range, i is first 0
i is not equal to 3 so 10 wouldn't be added but i would be added so
result = result + 0
Then i is 1 (coz its for loop, i is incrementing by 1) again result += 1
Then, result += 2
Now i = 3, so result += 10 would happen. Then result += 4 coz now i = 4.

Answer 2

0: result is 0
1: result is 1
2: result is 3
3: result is 13
4: result is 17
5: exit
Finally result is 17

Answer 3

I think the answer will be
1
2
3
14
5

As i iterates through the loop from 0 to 4, (<5) it checks the conditions before printing the result.
i0 +1 = 1
i1 +1 = 2
i2 +1 = 3
i3 + 1 = 14
i4 + 1 = 5
