Hey guys,

How would I go about doubling something EVERY instance. If I enter 1, x = 1. If I enter 2, x = 2. If I enter 3, x= 3 and so on and so forth. Trying to test something out.

Thanks guys!

B-80

what do you mean?

do{
x *= 2;
}while(whatever)

You asked about doubling, yet you said if you enter 1 you get 1, enter 2, get 2, etc. I'm missing something, but B-80 would be correct in his x *= 2 method while performing a loop.

basically, how do I double a penny for 30 days? That type of program.

First day you earn 1 cent.

Second day 2 cents.

Third day 4 cents.

Fourth day 8 cents.

Fifth day 16 cents.

And so on...

The "x *= 2" way. I assume you know, but in case you don't *= is short hand for x = x * 2. It's just a way of saving time.

for (int i = 0; x > 30; x++)
{
x *= 2
}

That's for Java at least.

And how would I get the sum of this then?

EDIT: Yes, I knew about the x *= 2. I was just commenting in regards to trying to explain myself better for ya'll.

Thanks man!

To get the final result? Just call x for calculations, or print out x to view the number.

are you talking about getting the sum of all the values of x?

if so, in the loop, you would do "y+=x"

Yes, but more complex than just calling x or printing it.
