void fill(double* expenses)
{
for (int i = 0; i < SEASONS; i++)
{
cout << "请输入" << Snames[i] << "季的费用:";
cin >> *(expenses + i);
}
}
void show(double* expenses)
{
double total = 0.0;
for (int i = 0; i < SEASONS; i++)
{
cout << Snames[i] << "季节的费用为:" << expenses[i] << endl;
total += expenses[i];
}
cout << "总的费用为:" << total << endl;
}
int main()
{
double expenses[SEASONS];
fill(expenses);
show(expenses);
Spend spend;
fill(spend.money);
show(spend.money);
