outFile C ++不写入输出文本 [英] outFile C++ not writing to output text

问题描述

下面是我的不完整的程序。我在写入文本文件时遇到问题。例如，我想写一个文本文件的雪天的数量，但在VS 2010中调试时没有在文本文件中显示。它显示我的信息和名称，但没有别的工作。之后不会写任何东西。它不写入文本文件。

  #include< iostream>信息信范范此预读亦范亦方范范范范范辛辛
 #include< string> 
 #include< fstream> 
 
使用namespace std; 
 
 const字符串INFORMATION =College Class;信中的内预范读亦读亦信息亦亦范范信息预读
 
 int main（void）
 {
 
 ofstream outFile; 
 
 
 int numberOfSnowDays; 
 int largestSnowDay; 
 int dayNumber; 
 double amounttOfSnow; 
 
 
 outFile.open（Ex1Out.txt）; 
 outFile<< （51）<信息< endl<< （48）< MY_NAME<< ENDL; 
 
 
 
 cout<< 请输入下雪天数：<< ENDL; 
 cin>> numberOfSnowDays; 
 outFile<< （10）< 下雪的天数是：<< （10）< numberOfSnowDays; 
 
 int index; 
 //问题1 for循环
 for（index = 0; index< numberOfSnowDays; index ++）
 {
 cout< 输入日期：<< ENDL; 
 cin>> dayNumber; 
 cout<< 输入积雪量：<< ENDL; 
 cin>> amountOfSnow; 
 
}; 
 
返回0; 
 
 
 
 $ b $ p 
 $ b 
这里是我的输出显示：
 College Class（居中） 
 Tom Hangler（居中） 
 
 
如果我在此之后尝试写入任何内容，则不会将任何内容写入输出文件。输出文本文件是在我的VS项目中包含我的.cpp文件。我添加了文本文件到项目。 
解决方案
 
尝试
  outFile.close（）; 
  
 
Down below is my incomplete program. I am having problems with writing to a text file. For example I want to write the number of snow days to a text file, but nothing shows up in the textfile when I debug in VS 2010. It does display my info and name, but nothing else works. It wont write anything after that. its NOT writing to a text file. 
#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>

using namespace std;

const string INFORMATION = "College Class";
const string MY_NAME = "Tom Hangler";

int main(void)
{

    ofstream outFile;


    int numberOfSnowDays;
    int greatestSnowDay;
    int dayNumber;
    double amounttOfSnow;


    outFile.open("Ex1Out.txt");
    outFile << setw(51) << INFORMATION << endl << setw(48) << MY_NAME << endl;



    cout << "Please enter num of days it snowed: " << endl;
    cin >> numberOfSnowDays;
    outFile << setw(10) << "Number of days of snow is: " << setw(10) << numberOfSnowDays;     

    int index;
    //Problem 1 for-loop
    for (index = 0; index < numberOfSnowDays; index++)
    {   
        cout << "Enter day: " << endl;
        cin >> dayNumber;
        cout << "Enter amount of snow: " << endl;
        cin >> amountOfSnow;

    };

    return 0;   
}
here is what my output displays:
College Class (centered)
Tom Hangler   (centered)


If i try to write anything after this, Nothing is written ever to the output file. And the output text file IS in my VS project that contains my .cpp file. I added the text file to project. 
解决方案
Try closing the stream at the end of the function, it looks like the data isn't getting flushed.
outFile.close();
