How to make sequential spawn of objects?

Question

C++ / C#

I have two positions where I need to spawn the Cube.
The logic is this, the cube should spawn on the left (I'll call the first position), then when I press the button, it should be deleted and the block should spawn on the right (second position)
How to implement this?

Answer 1

public GameObject[] cubes;

void OnClick()
{
    cubes[0].SetActive(false);
    cubes[1].SetActive(true);
}
