from solidity: TypeError

Question

from solidity: TypeError: Return argument type uint256 is not implicitly convertible to expected type (type of first return variable) int256. --> sample.sol:72:24:

cocontract fixedsizeArray{

    uint[5] public arr= [10,19,15,78,56];

    function array() public view  returns(int){
            uint odd;
            odd = arr[3];
            return odd;

    }
}

Answer 1

The arr array has defined as uint array. If you want return this array, you must change the returns values inside array() function from

int

to

uint

Like in this way:

pragma solidity ^0.8.0;

contract fixedsizeArray{

    uint[5] public arr= [10,19,15,78,56];

    function array() public view returns(uint){
        uint odd;
        odd = arr[3];
        return odd;
    }
}
