C++ C++；需要一个家庭作业程序的帮助，该程序从一个文件中读取一个双精度列表，并为每个双精度添加一个字符串

我在这个家庭作业计划上遇到了麻烦，现在我被困在了我应该做的事情上。程序从一个文件中读取12个双精度的列表。每个双精度代表一年中12个月的总降雨量（英寸），按月份顺序排列。12个双精度应写入一个数组。要求如下

这是我现在拥有的代码，我不知道需要在函数声明

displayRainsion

、

bubbleSort

、和

swap

中添加哪些内容，还需要在main中添加哪些内容：

// Headers
#include <iostream>     // cout, cin
#include <cstdlib>      // exit()
#include <string>       // strings
#include <fstream>      // file processing
#include <iomanip>      // stream manipulation
using namespace std;

// Global variables
const int MAX_MONTHS = 12; // months for rainfall
const string FILENAME = "TotalMonthlyRainfall2014.txt"; // The name of the file that is read

// Function declarations
int loadMonthlyRainfall (double rain[MAX_MONTHS], string fileName, int maxMonths);
void displayRainfall(string months[MAX_MONTHS], double rain[MAX_MONTHS], int monthCount);
void bubbleSort(double rain[MAX_MONTHS], int size);
void swap(int& a, int& b);

int main()
{
    int monthCount = 0;
    string months[MAX_MONTHS] = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
    double rain[MAX_MONTHS];

    loadMonthlyRainfall(rain, FILENAME, MAX_MONTHS);   

    //  Make sure we place the end message on a new line
    cout << endl;

    //  The following is system dependent.  It will only work on Windows
    system("PAUSE");

    return 0;
}

int loadMonthlyRainfall(double rain[MAX_MONTHS], string fileName, int maxMonths)
{
    ifstream inFile;        // Input file stream
    int numMonths = 0;

    // Open file
    inFile.open(fileName);
    if (!inFile)
    {
        throw "Can not open file";
    }
    //
    for (int r = 0; r < MAX_MONTHS; r++)
    {
        inFile >> rain[r];
    }
    // Close the file
    inFile.close();

    for (int r = 0; r < MAX_MONTHS; r++)
    {
        cout << rain[r] << " ";
    }
    cout << endl;

    return numMonths;
}

void displayRainfall(string months[MAX_MONTHS], double rain[MAX_MONTHS], int monthCount)
{

}    

void bubbleSort(double rain[MAX_MONTHS], int size)
{

}

void swap(int& a, int& b)
{

}

调用泡泡运动（降雨，最大月数）在

main

中进行以下更改：

void displayRainfall(string months[MAX_MONTHS], double rain[MAX_MONTHS], int monthCount)
{
    //title
    cout << "Monthly Rainfall for 2014" << endl;

    //print minimum rainfall
    cout << "Minimum: " << months[MAX_MONTHS-1] << " "<< rain[MAX_MONTHS-1] << endl;

    //print maximum rainfall
    cout << "Maximum: " << months[0] << " "<< rain[0] << endl; 

    //get and print average rainfall
    double avg = 0.0;
    for (int i = 0; i < MAX_MONTHS; i++)
    {
        avg+=rain[i];
    }
    avg = avg/MAX_MONTHS;
    cout << "Monthly Average for Year: " << avg << endl;

    //print ordered rainfall by month
    cout << "Sorted by Total Rainfall" << endl;
    cout << "Month" << setw(10) << "Inches" << setw(10) << endl;
    for (int i = 0; i < MAX_MONTHS; i++)
    {
        cout << setw(10) <<months[i] << setw(10) << rain[i] << endl;
    }
}    

void bubbleSort(double rain[MAX_MONTHS], int size)
{
    string months[MAX_MONTHS] = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
    //sort rainfall descending
    for (int i = 1; i < size; i++)
    {
        for (int j = 0; j < size - i; j++)
        {
            if (rain[j] < rain[j+1])
            {
                swap(rain[j], rain[j+1]);
                swap(months[j], months[j+1]);
            }
        }
    }
    //called inside bubbleSort because months and rain are sorted in scope
    displayRainfall(months, rain, 0);
}

void swap(int& a, int& b)
{
    int& temp = a;
    a = b;
    b = temp;
}
