C ++问题，不显示复制包含在其他文件上。

问题描述

您好，

我的程序中有一个问题是将一个文件复制到另一个文件中。它运行退出很好，但问题是它无法显示正确的输出。当文件Name.txt的包含已同步到另一个文件时，它不会显示复制的包含。请告诉我我缺少的东西。

该程序如下：



/ * WAP将一个文件的密码复制到另一个文件中* /

Hello,
I have a problem in my program of copying contains of one file into another file. It runs quit good but the problem is it can't show a proper output. When the contains of file "Name.txt" has coppied to another file then it doesn't shown the copied contains. Please tell me what I am missing.
The Program is follows:

/* WAP to copy containt of one file into another file */

#include<iostream.h>
#include<conio.h>
#include<fstream.h>
#include<stdlib.h>
void main()
{
ifstream infile;
ofstream outfile;
clrscr();
char infileName[10];
char outfileName[10];
char in_char;

outfile.open("Name.txt",ios::out);
outfile<<"Good\n";
outfile<<"To\n";
outfile<<"See\n";
outfile<<"You\n";
outfile.close();

cout<<"\nEnter file name to copy : ";
cin>>infileName;
infile.open(infileName,ios::in);
if(!infile)
{
cout<<"\nFile "<<infileName <<" not found ";
getch();
exit(0);
}
while(infile.get(in_char))
   cout<<in_char;
   infile.close();
cout<<"\nEnter name of new file in which you want to copy "<<infileName<< " : ";
cin>>outfileName;
outfile.open(outfileName,ios :: out);
if(!outfile)
{
cout<<"\n\aError in opening of "<<outfileName;
getch();
exit(0);
}
cout<<"\n\a\nFile Copy is in progress ......... ";
while(infile.get(in_char))
cout<<"\n\a\nFile Copy Sucessfull ...... ";
cout<<"\n\nNew File is : "<<outfileName;
cout<<in_char;
infile.close();
outfile.close();
getch();
}

输出：

输入要复制的文件名：Name.txt

好​​

到

请参阅

你



输入你想要的新文件的名称复制Name.txt：Read.txt



文件复制正在进行中.......



文件复制Sucessfull .....



新文件是：Read.txt





现在，它应该打印Read.txt的包含但不能打印它们。我试过但没有得到任何东西，所以请给我一些提示。

谢谢......

Output:
Enter file name to copy : Name.txt
Good
To
See
You

Enter name of new file in which you want to copy Name.txt : Read.txt

File Copy is in progress.......

File Copy Sucessfull.....

New File is : Read.txt


Now, here it should prints the contains of Read.txt but it can't prints them. I tried but didn't get anything, So please give me some hint.
Thanks...
