Question Regarding For Loops

[Creeder]

Hi all,

I am new to Java and basically have a question regarding the for loop.

The following code;

int poweroftwo;
int x;

for (int n = 1; Math.pow(2,n) < 100; n++)
{
poweroftwo = (int)Math.pow(2,n);
}
//Execute after for loop
System.out.println(poweroftwo);

However i get an error, Variable poweroftwo is not define, but when i use a while loop instead everything is fine.
Is there a difference?

Thanks in advance.

try initialising powereoftwo to 0. i copied and pasted what you had and set poweroftwo to 0 initially and then it worked fine.
