C Problem

i have a problem i do not either undestand or know how to solve..
i am using visual c++ 6 ( i am new to c++)

considering the following simple code

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

int main(void)
{
ofstream my_file("c:\test.txt");

my_file<<"This text will now be inside of test.txt";

my_file.close();

return 0;

}


the compilation goes fine
but when i try to build the exe i get the following:

LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/Hello3.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

could anyone tell me what's going on? thanx in advance

I don't actually know c, but I do more or less know php, and I was thinking it might be because your

Doesn't end with a semicolon, ;
Hope this helps

The error is in the linker. The way I fixed this problem was to open a new project in VC++ and paste the old code and recompile it. I have no idea why it does this, and I know for a fact there are others that know the linker error codes.

ammo, any ideas?

im pretty sure that int main(void) doesnt end with a semicolon since it isn't a statement. I could be wrong, im new to c, and recently read that only statements end with the semicolon. Other than that, i dont know the error, you might wanna ask ammo, he is the programming king. or rioter, hes good too.

putting a ; after int main(void) would not be correct thing to do. It has been a while but I think either you are missing an include file or you have called a external function by an incorrect name. It has been a very long time since I did C though.

thats right, int main(void) does not to have a semicolon, only if it is your function prototype which it isnt.

Does your compiler come with help files? Some compilers come with documentation of compile and link errors.

I did a web search for you and this site http://www.cs.northwestern.edu/acade...html/bugs.html apears to have an answer for you. I simply did a search for

"LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
"

with the quotes.

I copyed the folowing from the area of the site:

============================================

Linker error "unresolved external symbol _WinMain@16"
Linking...
LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16

You have named your source file name.cpp . Rename it to name.c
You have created the wrong type of project. Create a Win32 Application for graphics and a Win32 Console Application for projects with no graphics.

Hey, that was a great find, I always wondered about the error messages, and was not all that clear even on MSDN. I will give the link to the C++ teacher...

Make sure it is a console app and not a windows app. This is done in the project settings.

Cheers,

-D

and it should be

int main()
{
or

int main (int charc, char* argv[])
{

either way no ; -thought I'd [pound the dead horse

Like the others said, you probably created the wrong type of project with Visual C++....
Make sure you create a console app...

Ammo

BTW, you should have said a "C++ problem" as your code is C++...
