So i'm confused about this part

if ( i % 12 == 0)
		{
			cout << "i = " << i << endl;
		}

i % 12 means get the remainder of i which is zero divided by 12 is equal to zero?
then i increments by 1 and now it's i is 1? divided by 12?
I'm confused now.

#include <iostream>

using namespace std;

int main()
{

	for (int i = 1; i < 1000; i++)
	{
		if ( i % 12 == 0)
		{
			cout << "i = " << i << endl;
		}
	}
}

Why it starts counting at 12? I initialize variable to 1 but it started as 12?

Could someone explain this better to me line by line how this program .
I just started to today learning c++ and didn't expected programming is very confusing but it's fun.

It means the remainder of the division i / 12. It's not always zero. Think about it. When does it happen?
