返回垃圾數量，我不知道爲什麼

Question

我試圖創建一個程序，從文件中讀入數組中的數字，顛倒數組中的數字的順序，然後將這些顛倒的數字輸出到不同的文件。當我已經知道文件中有多少個數字時，我能夠使程序工作，但當我將循環切換到嘗試檢測EOF（文件結束）時遇到困難。當我運行這段代碼時，它會從文件中打印兩個數字，其餘的都是垃圾數值。任何幫助？

#include "stdafx.h" 
#include <iostream> 
#include <fstream> 
#include <string> 

using namespace std; 

const int NUMS = 5; 

void reverseArray(int number[], int first, int last) 
{ 
    int temp; 

    if (first >= last) 
    { 
     return; 
    } 

    temp = number[first]; 
    number[first] = number[last]; 
    number[last] = temp; 

    reverseArray(number, first + 1, last - 1); 
} 

int main() 
{ 
    //Create file objects 
    ifstream inputFile; 
    ofstream outputFile; 
    string inputName; 
    string outputName; 

    //Prompt user for file names 
    cout << "What is the name of the input file?" << endl; 
    getline(cin, inputName); 

    cout << "What would you like the output file to be called?" << endl; 
    getline(cin, outputName); 

    //open user named files 
    inputFile.open(inputName); 
    outputFile.open(outputName); 

    int numsFromFile; 

    int numbers[NUMS]; 

    int fileCount = 0; 

    /* 
    //read in numbers from a file ********THIS WORKS BUT WHEN I CHANGE IT BELOW IT DOES NOT****** 
    for (int count = 0; count < NUMS; count++) 
    { 
    inputFile >> number[count]; 
    } 
    */ 

    //Try to read numbers in detecting the EOF 
    while (inputFile >> numsFromFile) 
    { 
     inputFile >> numbers[fileCount]; 
     fileCount++; 
    } 

    //print numbers to screen 
    for (int count = 0; count < fileCount; count++) 
    { 
     cout << numbers[count] << endl; 
    } 

    //reverse array 
    reverseArray(numbers, 0, 4); 

    cout << "Reversed is: " << endl; 

    //print reversed array 
    for (int count = 0; count < NUMS; count++) 
    { 
     cout << numbers[count] << endl; 
    } 

    //output numbers to a file 
    for (int count = 0; count < NUMS; count++) 
    { 
     outputFile << numbers[count] << endl; 
    } 

    outputFile.close(); 
    inputFile.close(); 

    return 0; 
}

有一個在線路中的錯誤：你最終的閱讀和丟棄的第1個數字，第三號，第五號等將其更改爲

while (inputFile >> numsFromFile) 
{ 
    inputFile >> numbers[fileCount]; 
    fileCount++; 
} 

：

while (inputFile >> numsFromFile) 
{ 
    numbers[fileCount] = numsFromFile; 
    fileCount++; 
}
