此程序允许用户输入每个季节的费用，然后显示值，然后显示底部的总费用。但是，它给了我这个错误

我该如何解决这个问题？

#include <iostream>
#include <array>
#include <string>

// constant data
const int Seasons = 4;
const std::array<std::string, Seasons> Snames =
    {"Spring", "Summer", "Fall", "Winter"};

// function to modify array object
void fill(std::array<double, Seasons> * pa);
// function that uses array object without modifying it
void show(std::array<double, Seasons> da);

int main()
{
    std::array<double, Seasons> expenses;
    fill(&expenses);
    show(expenses);
    return 0;
}

void fill(std::array<double, Seasons> * pa)
{
    using namespace std;
    for (int i = 0; i < Seasons; i++)
    {
        cout << "Enter " << Snames[i] << " expenses: ";
        cin >> (*pa)[i];
    }
}

void show(std::array<double, Seasons> da)
{
    using namespace std;
    double total = 0.0;
    cout << "\nEXPENSES\n";
    for (int i = 0; i < Seasons; i++)
    {
        cout << Snames[i] << ": $" << da[i] << endl;
        total += da[i];
    }

cout << "Total Expenses: $" << total << endl;
}
