返回垃圾数量，我不知道为什么

Question

我试图创建一个程序，从文件中读入数组中的数字，颠倒数组中的数字的顺序，然后将这些颠倒的数字输出到不同的文件。当我已经知道文件中有多少个数字时，我能够使程序工作，但当我将循环切换到尝试检测EOF（文件结束）时遇到困难。当我运行这段代码时，它会从文件中打印两个数字，其余的都是垃圾数值。任何帮助？

#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; 
}

有一个在线路中的错误：你最终的阅读和丢弃的第1个数字，第三号，第五号等将其更改为

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

：

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