Why did we use payable for array and to push into an array

[kaushikc44]

Why are we using payable before address [] array and while trying to append into the array. How does it matter if we don't use payable either way until the user does not pay inside the array it can't be pushed right ?

    uint256 public immutable i_priceRaffle;
    address payable[] private s_player; 

    event RaffleEnter(address indexed player)

    constructor(uint256 priceraffle) {
        i_priceRaffle = priceraffle
    }

    function enterRaffle() public payable{
        if (msg.value < i_priceRaffle){
            revert(Raffle_SendMoreEth());
        }
        s_player.push(payable(msg.sender))
        emit(RaffleEnter(msg.sender))
    }

    function getRafflePrice() returns(uint256 _price){
        return i_priceRaffle
    }
}```

@kaushikc44 payable addresses are different from regular addresses, this payable keyword tells solidity that these addresses will receive the ethers.

Okay still dont get why do we need to put payable both the places even while pushing

@kaushikc44 read it you will get it link

@kaushikc44 Because msg.sender address is not payable, so we need to convert it to payable address to fit the array of payable addresses

[kaushikc44]

Makes more sense now, only those accounts fund that are paying for it raffle correct ?
if the above statement is correct.
Also, I understood why it should be payable but while pushing or appending into the array why do we have to define it again as payable ?

[alfaqi]

we don't define it again as payable, just one time (while pushing into the array).
and you can't push address to this array, until you convert it to payable.
