Are you using C++ or C ? fopen is C. ifstreams are C++. In C++, reading a file with an ifstream, you can use the getline function to read a line at a time, and of course, you can keep count as you do so.

It's a sign from God. If you want more info, try posting the actual error, so we have something to work with.

an unresolved external symbol linker error occurs when a compiled file (but not linked yet) uses an external symbol, such as a function or a variable declared as extern, but found nowhere in the reste of the project files.
that's why we have to #include some files sometimes...
the linker cannot find for beginthreadex() and endthreadex() for two major reasons...
1) you didn't wrote the function names correctly (C/C++ are case sensitive, so be careful to the caps...).
2) you don't include the correct header file (.h)where these two functions are defined. as they are standard headers (not defined in your project, but in one of the compiler folder), use #define<>.

Do you mean I need to add in #define beginthreadex and #define endthreadex at the beginning of the program
|
|
|
|
|
#define ???? no never, i never talked about that, i said #include

After I add the #include <beginthread> and #include <endthread>
its still got error
error C1083: Cannot open include file: 'beginthreadex': No such file or directory

please edit your previous post and uncheck the "Do not treat <'s as HTML tags" checkbox down EditBox you type the post

the #include file is not in the same directory where ur application is present
so #include foldername//abc.h
foldername in which abc.h is present

When I build a console application , it always appears with the default application icon (the blue buildings). How can I change this icon?

Have you tried simply adding an icon to your app using the resource editor in Visual Studio? That should be enough.

I've just tried to do this, and managed to get it to work. Here's what you do...
In VC++, select the following menu item: "Project" -> "Add To Project" -> "New..."
From the resulting window select to add a Resource Script (give it any name, I don't think it matters). You'll now have a "Resources" tab added to your project from which you can right-click and do "Insert...", and select Icon from the resulting box. Then just edit your icon.
Worked for me.
I guess it would work just as well if you selected "Import..." instead of "Insert...", and selected a pre-defined .ico file.
Hope this helps, 'bod
