C++ use function's output as functions input n times

I’m sorry for the weird title. I don’t know how to word this.
If I have function func()
How do I do this:

func(func(func(func(func(x)))))

where it repeats N times?

I’m trying to implement Conway’s Game of Life. I have a function that takes a vector and outputs another vector, which is the next generation of the input vector. So generation 3’s vector would be func(func(func(x))).

>Solution :

The easy way, simply using for loop:

int x = some_initial_value;
for (int i = 0; i < NUMBER_OF_ITERATIONS; ++i)
{
    x = func(x);
}
