Initialize an array with different index starting point to any N?

I've been sitting here for a few hours now, trying to figure out how an array can be initialized with specified array[index], no not 0-n, but n-N, meaning that index can be: 3, and then it increments to N.

int array[];
std::iota(std::begin(array), std::end(array), 2);

That line does one thing, but not what I want. Since I filling up the values of the array as bool and setting all to false by default, but, index goes from 0-N.

Is it possible:

int array[std::advance(iter, 2)]

When I run, std::iota(std::begin(array), std::end(array), 2); then output below looks as that, but, I want it to be: [2]:false, [3]:false, ... N.

Output:

[0]:2
[1]:3
[2]:4
[3]:5
[4]:6
[5]:7
[6]:8
[7]:9
[8]:10
