如何在函数中传递 2 个值?

How can I pass 2 values in a function?

现在我正在尝试将 name 和 argc 传递给投票函数

但是我遇到了一堆错误,argc 不起作用,我该如何传递它?

我有 2 个错误说我在函数调用中有很多参数。

它说它只需要一个参数。

int main(int argc, string argv[]) // I want to pass this argc parameter into my vote function
{
    // Check for invalid usage
    if (argc < 2)
    {
        printf("Usage: plurality [candidate ...]\n");
        return 1;
    }

    // Populate array of candidates
    candidate_count = argc - 1;
    if (candidate_count > MAX)
    {
        printf("Maximum number of candidates is %i\n", MAX);
        return 2;
    }
    for (int i = 0; i < candidate_count; i++)
    {
        candidates[i].name = argv[i + 1];
        candidates[i].votes = 0;
    }

    int voter_count = get_int("Number of voters: ");

    // Loop over all voters
    for (int i = 0; i < voter_count; i++)
    {
        string name = get_string("Vote: ");

        // Check for invalid vote
        if (!vote(name, argc)) // it doesn't work here
        {
            printf("Invalid vote.\n");
        }
    }

    // Display winner of election
    print_winner();

bool vote(string name, int argc) // and here
{
    // TODO
    return false;
}

}

答案在最后一个错误中:

plurality.c:23:6: previous declaration is here

bool vote(string name);
