What is the answer of the following code snippet and explain how you get the answer

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);

Answer 1

Initially the value of result = 0
➡️ Now for i=0, the if i==3 condition is false, so result = 0+0 i.e. result will be zero
➡️ Now for i=1, the if==3 condition is false, so result = 0+1 i.e. result will be 1.
➡️ Now for i=2, the if ==3 condition is again false, so result = 1+2 i.e. result will be 3.
➡️ Now for i=3, the if condition will be true as I==3 is true so the value of result will be 3+10 = 13
➡️ Now for i=4, the if condition is false, so result = 13+4 i.e. result will be 17.
➡️ Now the loop stops iterating as i<5 condition is false. So it comes out of the loop and print the value of result i.e. 17.

Hope this is helpful 😅

Answer 2

For i=0 : i != 3 , so (result += 10) will not be executed , we skip to the else statement : result += i : so result = 0+0 = 0.

For i=1 , the same case , we execute the else statement : so result=0+1 = 1

For i=2 , result = result + i = 1 + 2 => result = 3

For i=3 , the condition is verified here , so we execute ( result +=10 ) => result = 3+10 = 13

For i=4 , result = result + 4 => result = 17

For i=5 , the loop' condition i<5 is not verified , then the end of the loop.

The output is : 17

thank you very much it all make sense now
