Hello,
I am a new member so please no offense.
Does it matter if i do this:
1. int i;
2. for(i = 0; i < 10; i++)
3. {
expression
}

so does it matter if the 1. number would be this or this:
int i = 0;
OR
int i;

Does it matter?

Thank you!

Doesn't matter, since you're initializing i twice - once at instantiation and once when you setup your loop. In modern C++, it's common to use a "for(int i=0;..." form, so that i is scope-limited to the loop. The theory is that it makes your program more resilient to later updates.
