Dev-C++ Trouble

[Thadius Dean]

when i try to compile a program, the half-life program "iostream.h" appears as a new tab and makes it impossible to compile because the "#include "backward_warning.h" or line 31:1 makes an error.

if you want to see the code that pops up its;

...help?

um, "the half-life program "iostream.h""?

post the error message and we may be able to help

The unit you are trying to compile would probably help too.

iostream.h is deprecated.
Change your code to "#include <iostream>" and put "using namespace std;" after that (or manually tell it to use std::cout, whatever you need).

[edit]
With changing your code to "#include <iostream> I mean, changing the "#include <iostream.h>" to "#include <iostream>". No quotes.
[edit2]
In case you're trying to compile the HL SDK, I'd really go with MSVC6 (or higher). The SDK simply won't compile with MingW without chaning a bunch of stuff.

well im absolutely new to programming, im still working out a simple c = a - b program, so i understood nothing of what any of you just said

i think the error message is "31 C:\Dev-Cpp\include\c++\backward\iostream.h
In file included from C:/Dev-Cpp/include/c++/backward/iostream.h
"
i uninstalled the source code, i uninstalled and redownloaded Dev C++ but those still didnt work.

 

[Varsity]

Please post the code you have written.

 

[Thadius Dean]

its not the code that did it the first time, but it happens every time so this should count.

#include <iostream.h> 

int main() 

{ 
    int a, b, ans;
    
    cout << "What is your first number?";
    cin >> a;
    
    cout << "What is your second number?";
    cin >> b;
    
    ans = a - b
    
    cout << "Your first number minus your second number is";
    cout << ans;
	
 return 0;

}

Instead of

#include <iostream.h>

in your code, write:

#include <iostream>

using namespace std;

since the iostream.h header is deprecated and shouldn't be used.

because that code is wrong as of about 1998, change the <iostream.h> to <iostream> and place either 'using namespace std;' at the top of the code (after the #include) or at the top of the function or place std:: before all the cout and cin lines.

That however will only fix that code, my advice, get a better tutorial/book as the one you are using is wrong, You need to get one which teaches you proper C++ and uses the standard namespace.

If this error is accuring while recompiling the HL SDK then you'll need to fix the file to work, however if you are only just learning C++ that is beyond the scope of that i can explain to you right now, my best advice is go away and learn the basics properly.

 

[Thadius Dean]

well, i dont have a book yet, just usin' that cplusplus tutorial.
ok ill put that in and try it out...

sweet, it works, now im only getting regular error messages

thanks guys.

 

[skull24]

I know alot of C++ but....

I mean, do you guys think this book called "Half-Life 2: Mod Makers Prima Strategy Guide " will help me or anyone else learn more about MODing in HL2 or for any other game. The cover looks good....lol

Well, I am buying it just to see how it is, someone should e-mail Valve and find out what they think. If you do a search for it on google.com or yahoo.com, I know you can find it.
