contract Voting {
    ///@dev keeps track of the voter candidates' info
    struct VoterCandidate {
        string voterName;
        uint voterAge;
    ///@dev keeps track of all the candidates
    VoterCandidate[] public candidates;

    ///@dev creates a new "VoterCandidate" and adds a the candidate to the array of candidates
    function candidateRegistration(string memory _voterName, uint _voterAge) public {
        VoterCandidate memory newCandidate;
        newCandidate.voterName = _voterName;
        newCandidate.voterAge = _voterAge;
