variable reassignment

[osuman]

If I declare a variable, such as an int and set it equal to an initial value, will it get reset if it is in a loop to it's initial value on each iteration. For example, consider the following code:

for(int i=0; i<whatever; i++) {
int j = 0;

some other code that changes the value of j...
}

Now if I want j to get set to 0 each time the loop iterates, will it do so with the above example? Obviously, a simple solution would just be to split up the declaration and instantiation into seperate lines. But I was curious what the deal is.

Thanks.

Yes, it will create a new variable each time and initialise it to 0.

I don't think you create a new variable each time. Only the initialisation will happen each time. ??

I didn't think it would create a new variable each time. That seems like it would use a lot of unnecessary space. I figured if it had already been initialized it wouldn't do it again on successive loop iterations. This led me to wonder if it would set it equal to 0 or skip the statement entirely. Does anyone know for sure?
