I'm sure I know what you meant by this, but do you mean create a local variable to the function foo? (I'm pretty sure thats what you meant, just making sure and clarifying it for Mr.Gruntsworthy just in case )

Yes.

Any specific reason we are doing that then? Is this going to be something to be built upon eventually?

[wtd]

Scope is a very important concept.

please explain a little further; it's morning and my brain hasn't booted up yet, lol.....

You have your function:

code:

int foo(int x, int y) {    return ((x * x) * y) + 1 }

I would like you to rewrite this such that the result of:

code:

x * x

is stored in a variable called "bar". This variable must be scoped locally to the function "foo". That is, it should not exist outside of the "foo" function.

damnit i hate it when people use such high levels of tech talk and can't use simple english. My brain is on 'safe mode' and has been for the last week.

[wtd]

Let me demonstrate.

code:

void a() {    some_type b = some_value;    do_something_to(b); }

Here the variable b is scoped as local to the function a.

I think i see....

I have alot to learn before i start attending the International Academy of Design and Tecnology in July.

Yes, but you have a fair amount of time. Think of it as a challenge, and you will do well.

What you need to do is write code. Write a lot of code. That doesn't mean it has to be huge programs, but rather lots of small projects.

Submit those small programs for frequent critique. Such critiques can be pretty critical, but that's the point.

[Mr. Gruntsworthy]

well, if i find time to submit anything i've written, ill do so.
