So, I don't know if anyone actually cares about my "blog", but if anyone is reading this... can someone explain why this is a struct instead of a class?

[SELECT ALL] Code:

struct voteinfo
{
    int boot;
    int owner, callmillis, result, num1, num2, type;
    char text[MAXTRANS];
    serveraction *action;
    bool gonext;
    enet_uint32 host;

    voteinfo() : boot(0), owner(0), callmillis(0), result(VOTE_NEUTRAL), action(NULL), gonext(false), host(0) {}
    ~voteinfo() { delete action; }

    void end(int result)
    {
        if(action && !action->isvalid()) result = VOTE_NO; // don't perform() invalid votes
        sendf(-1, 1, "ri2", SV_VOTERESULT, result);
        this->result = result;
        if(result == VOTE_YES)
        {
            if(valid_client(owner)) clients[owner]->lastvotecall = 0;
            if(action) action->perform();
        }
        loopv(clients) clients[i]->vote = VOTE_NEUTRAL;
    }

    bool isvalid() { return valid_client(owner) && action != NULL && action->isvalid(); }
    bool isalive() { return servmillis - callmillis < 30*1000; }

    void evaluate(bool forceend = false)
    {
        if(result!=VOTE_NEUTRAL) return; // block double action
        if(action && !action->isvalid()) end(VOTE_NO);
        int stats[VOTE_NUM] = {0};
        int adminvote = VOTE_NEUTRAL;
        loopv(clients)
            if(clients[i]->type!=ST_EMPTY /*&& clients[i]->connectmillis < callmillis*/) // new connected people will vote now
            {
                stats[clients[i]->vote]++;
                if(clients[i]->role==CR_ADMIN) adminvote = clients[i]->vote;
            };

        bool admin = clients[owner]->role==CR_ADMIN || (!isdedicated && clients[owner]->type==ST_LOCAL);
        int total = stats[VOTE_NO]+stats[VOTE_YES]+stats[VOTE_NEUTRAL];
        const float requiredcount = 0.51f;
        bool min_time = servmillis - callmillis > 10*1000;
#define yes_condition ((min_time && stats[VOTE_YES] - stats[VOTE_NO] > 0.34f*total && totalclients > 4) || stats[VOTE_YES] > requiredcount*total)
#define no_condition (forceend || !valid_client(owner) || stats[VOTE_NO] >= stats[VOTE_YES]+stats[VOTE_NEUTRAL] || adminvote == VOTE_NO)
#define boot_condition (!boot || (boot && valid_client(num1) && clients[num1]->peer->address.host == host))
        if( (yes_condition || admin || adminvote == VOTE_YES) && boot_condition ) end(VOTE_YES);
        else if( no_condition || (min_time && !boot_condition)) end(VOTE_NO);
        else return;
#undef boot_condition
#undef no_condition
#undef yes_condition
    }
};
