How can I iterate through an array into my class

Question

I'm trynna implement my function "isCellAliveAtPosition" who takes an integer in argument which is the position(index) of an element of the array.
I want to get something telling me that my cell is alive at that position if there is true value(1) and dead if died (0)
I tried many things but with OOP it's harder for me

Answer 1

Can you explain to me what the class constructor and buildFixedWorld method was supposed to actually do? I think I'm a bit lost there.

And why you make `$cells` member public when you also have a pair of getter and setter?

Answer 2

This is what I came up with, can you check it out once?

Answer 3

Regarding the encapsulation of cells I was wrong , it's a private variable.

The constructor take the number of cells in argument, and initialize the cells array with 100 false boolean values.

The buildFixedWorld create an instance of WorldState and has to make 5 cells "alive" so the value of 5 of them must be from false to true
But it's another thing I didnt do it well
