What is the output of the following Processing code fragment?

What is the output if the last part of the loop header is changed to “i = i + 2”?

int i;

int x;

for (i = 0; i < 25; i = i + 1)

{

x = (i * i) + 2;

println("Next value: " + x);

}

I am completely confused, do not even know where to begin(very new to processing). Any tips or suggestions would be greatly appreciated!

like you may know, this question isnt clear at all lolll
you must tell me what is your objective. What result you'd like to reach?
and,
why do you ask "What is the output" ... println will show you the output ... or maybe you must be more precise there

cheers

This is just a homework question I copy and pasted onto here, very confusing to me...Maybe what is the new output when the loop header is changed to “i = i + 2”?

You need to learn to start writing meaningful subjects to your questions... Apparently you always need help asap :/

As for where to begin.... Did you try pasting the code into Processing and running it? I'm not sure I understand your confusion... Or is it simply that you want us to do your homework for you? Anyway... The 'output' is produced by println(), which writes text to the output window (at the bottom of the Processing editor) when you run the code.

Presumably you're being asked to descibe the number sequence that the equation in the for loop produces. In the first case each repetition of the loop sees 1 being added to the value of i (i.e. you get 0,1,2,3,4...etc) and this is fed into the equation. If you change the loop so that i = i + 2, then you're only passing even numbers to the equation (i.e. 0,2,4,6,8....etc).

If that still doesn't make sense you may need to clarify where you're having problems...
