Problem writing into 2 text files

[Tullius]

I have the following problem when I try to run a simple writing to a text file: for the first text file : "alfa.txt" the program works fine, but for the "beta.txt" text file the program stops working and I can't write anything to it. Here is the source code:

#include<iostream.h>
#include<fstream.h>
#include<stdio.h>

void main()

{char ch1,ch2;

fstream f1("alfa.txt",ios::out);
fstream f2("beta.txt",ios::out);
while(cin>>ch1)
f1<<ch1;
f1.close();

while(cin>>ch2)
f2<<ch2;
f2.close();

}

Can anybody help me with this thing?
Thank you very much!

What exactly do you want to write to alpha and beta files?

[Tullius]

Mainly names, and for alfa file it works fine, I write the names, then i hit Ctrl+Z to finish the reading from the keyboard and when I want to do the same thing with beta file (the second while) it won't work. The window turns inactive!

Insert cin.clear(); before while(cin>>ch2) .
After you you pressed Ctrl-Z cin is in eof state. cin.clear(); clears the state and allow to continue work.

I just tried cin.clear(); and I get the same thing...nothing. could you please try and run this code on your compiler and see what do you get?

#include<iostream>
#include<fstream>
#include<stdio.h>
using namespace std;

int main()

{char ch1,ch2;

fstream f1("alfa.txt",ios::out);
fstream f2("beta.txt",ios::out);
while(cin>>ch1)
f1<<ch1;
f1.close();
cin.clear();
while(cin>>ch2)
f2<<ch2;
f2.close();

}

worked on Linux (with Ctrl-D - as end of input) and works on Windows (but before and after Ctrl-Z I need to press Enter)

[Tullius]

At last! It worked ! The problem was my version of C++, I was working on the 3.1 version. Now I've downloaded the 5.2 version and it works like a charm, exactly as you've said - by pressing Enter before and after hitting Ctrl+Z.

Thank you very much for your help!

I have another question. Now the program works fine and writes the names into the text files. But how can I sort alphabetically the names into the two text files? Can you give me an example?
