End of cin

[newbiecpp]

I have a simple program:

int main()
{
string buffer;
while( cin>> buffer)
cout << buffer << " ";

return 0;
}

When I input string from console, how can I stop input? I click "CTR+D" but
it won't work?

Thanks in advance.

char strMyString[100];

I always do a cin.get(strMyString, '\n');

Then it will get the string until you hit the Enter key... : ) (I think..
..heh)

That depends on the environment in which the application is started.

I click "CTR+D" but it won't work?

That works under Linux (and other unixes I think). For Windows, try
Ctrl-Z.

Ctrl+C will do it.

Alternatively you can build in an exit into your while loop,
e.g. q for quit:

#include <iostream>
#include <string>
using namespace std;

int main()
{
string buffer;
while ((cin >> buffer) && (buffer != "q"))
cout << buffer << " ";

return 0;
}

Thanks, Ali.

CTR+D works fine with Unix, but I tried every "CTR+any key" in Windowns, it
just didn't work! What's happen under Windows?

Sorry to get out of topic for this newsgroup but apparently you need to
hit Enter after pressing Ctrl-Z under Windows.

This maybe because the input is line-buffered and requires a new line to
hand the line over to the application. (?)

use cin.eof()

use cin.eof()

cin.eof() just tests for end-of-file, which (cin) also does. The
question, I think, was how the user can trigger eof.
