I am little bit confused about this equation. How this code result to 6 ?

Question

int i;
for(i = 1; i <=5; i++);

System.out.print(i);

Answer 1

Your reasoning is found in this:

i <=5;

^Varible 'i' starts off at 0 and is ending at 5 (less than-equal to). 0-5 is 6 spaces. If you did i < 5 then it would display 5 numbers (0-4) rather than 6 numbers.

Also, you're declaring variable 'i' twice, so you'll prob run into compile issues. Remove 'int i' from before the loop.

Also, put a check next to Xan's answer instead of placing your own comment as the correct answer to the question/thread.

Answer 3

6 is never output. I think you mean why is System.out.print(i) called 6 times.

it's the <= which means Less Than OR Equal.

5 is less than or equal to 5.

Also, no need to declare i twice.

I think Kent it was challenge question so if you want output 6: then this is may be coding question

Answer 5

sorry...i edit one that need corrections..

thank you for your answers..i understand it now...👍👍

Answer 6

I believe Jakob is incorrect. I is 6 by the time it is printed because the i++ in the loop adds 1 once after the final i<=5 evaluation.

The i=1 part of the for loop resets i to 1 when the for loop starts the first time
