How to retrieve from a specific index in an array?

[zchuanru]

Hi All!

I tried to create a simple code to input and retrieve from a specific index in an array.
My code so far:

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract test {

    uint256[] public moneyArray;

    function moneyPush(uint256 _moneyInput) public {
        moneyArray.push(_moneyInput);
    }

    function moneyGet (uint256 _moneyArrayIndex) public view returns(uint256) {
        return moneyArray[_moneyArrayIndex].retrieve();
    }
}

It seems uint256 does not have the retrieve function.
What do I need to use instead?

Thank you

Hi sorry,

I found the correct code:

    function moneyGet (uint256 _moneyArrayIndex) public view returns(uint256) {
        uint256 moneyGetVar = moneyArray[_moneyArrayIndex];
        return moneyGetVar;
    }
