// Update ranks given a new vote
bool vote(int rank, string name, int ranks[])
{
    // TODO
    for (int i = 0; i < candidate_count; i++)
       {
        if (strcmp(name, candidates) == 0)
           {

            //NEED TO INCREMENT VOTES RECEIVED BY CANDIDATES BY 1 FOR RANKS[J]
            preferences[rank] = preferences[rank] + 1;
            printf("rank is %i", preferences[rank]);
            return true;
           }
       }
    return false;
}

    Not sure if I am moving in the right direction. By the above vote function, no. of votes for a particular rank getting incremented by 1. Is that the objective of the vote function?
