Voting smart contract help highest voted function?

Question

first, I apologize for this very simple question. I'm starting my studies on smart contract can someone explain highest voted function in this contract?

contract Voting{

    string[] public members;
    mapping(string => uint) public memberVote;
    mapping(address => bool) public voted;

    function addMember(string memory name) public {
        bool repeated=false;
        for(uint i=0; i < members.length; i++){
            if(keccak256(abi.encodePacked((name))) == keccak256(abi.encodePacked(members[i]))){
                repeated = true;
            }
        }
        if(repeated==false){
            members.push(name);
            memberVote[name] = 0;
        }
    }

    function Vote(string memory name) public{
        require(voted[msg.sender]==false, 'one address one vote');
        memberVote[name] = memberVote[name]+1;
        voted[msg.sender]=true;
    }

    function highestVoted() public view returns(string memory){
        uint maxIndex=0;
        uint maxVote=0;
        for(uint i = 0; i<members.length; i++){
            if(memberVote[members[i]]>maxVote){
                maxIndex=i;
                maxVote=memberVote[members[i]];
            }
        }
        return members[maxIndex];
    }

    function getMembers() public view returns(string[] memory){
        return members;
    }
    function getVotes(string memory member) public view returns(uint){
        return memberVote[member];
    }

}

Answer 1

No need to apologize :) we all start somewhere!

The highestVoted function in this contract is used to find the member with the highest number of votes. Here's a breakdown of how it works:

Initialize two variables, maxIndex and maxVote, to store the highest-voted member's index and vote count.

   uint maxIndex=0; // Index of the highest-voted member
   uint maxVote=0; // Count of votes

Loop through the members array with a for loop.

for(uint i = 0; i<members.length; i++)

For each member, check if their vote count is greater than the current maxVote.

if(memberVote[members[i]]>maxVote)

If a member's vote count is higher, update maxIndex to their index and maxVote to their vote count.

maxIndex=i; // Update the maxIndex
maxVote=memberVote[members[i]]; // Update maxVote (higher than the previous)

After the loop completes, return the member with the highest vote count using members[maxIndex].

  return members[maxIndex];

This function determines the current leader in the voting process.

Answer 2

Highest Voted Function Contract function that counts and performs a specific action when a certain number of votes is achieved in the system.

addMember(string memory name) public Vote(string memory name) public

function addMember(string memory name) public { // function body here }

function Vote(string memory name) public { // function body here }

highestVoted() public view returns(string memory) function highestVoted() public view returns (string memory) { uint maxIndex = 0; uint maxVotes = 0;

for (uint i = 0; i < members.length; i++) {
    if (memberVote[members[i]] > maxVotes) {
        maxVotes = memberVote[members[i]];
        maxIndex = i;
    }
}

return members[maxIndex];

getMembers() public view returns(string[] memory) function getMembers() public view returns (string[] memory) { string[] memory activeMembers = new string; uint activeIndex = 0; for (uint i = 0; i < members.length; i++) { if (memberVote[members[i]] > 0) { activeMembers[activeIndex] = members[i]; activeIndex++; } } return activeMembers; }

getVotes(string memory member) public view returns(uint) function getVotes(string memory member) public view returns (uint) { require(memberVote[member] > 0, "Member does not exist or has no votes."); return memberVote[member]; }
