Rule Round Up #30 - What?? for loop declarations

[Janeice DelVecchio]

Is this legal?
int i;
for (i = 4, int t = 6; i < 0; i++)

Answer: No.
You can declare or initialize more than one variable in a for loop, but you can't mix declarations with initializations.

What? It's telling me I can do it in the answer, but it's telling me that it's wrong.

So what does one look like that is correct?

They mean that you can declare and initialize multiple variables

for(int i=0, j=0; i<10 && j<10; i++, j*=2){}

And only initialize more variables:

int i;
int j;
for(i=0, j=0; i<10 && j<10; i++, j*=2){}

But you can't mix it.

int i;
for(i=0, int j=0; i<10 && j<10; i++, j*=2){}

Ahh.... I get it now! Thanks, Wouter!
