Get an error when I try to compile this(C++)

Code: [Select]

//Oefening1: Klassen en objecten
#include <iostream.h>

//De klassendeclaratie
class Breuk
{

public:

void Tonen();
};

//De klassedefinitie
void Breuk::Ingeven()

cin>>teller>>noemer;
}

void Breuk::Tonen()

The error is

HB Very few people here speak german, let alone speak german and c++, so english plz  ???

So what! I wanna get out! 'Cos there's so much out there! So many different people, living different lives! Incredibly good guys, bad guys... Folks completely different from us! It's one huge melting pot! See, it's not about success, dying in the streets, who's better, who's not! I just want to be a part of it! I realized that even if I've no connections, no talent, even if I'm one big loser, I want to use my hands and feet to think and move, to shape my own life! We can just die here or we can try, see what we've got!

iostream.h is depreciated use iostream.

Re: Get an error when I try to compile this(C++)

fatal error C1083: Cannot open include file: 'iostream.h': No such file or directory

It seems that your compiler cannot find iostream.h ..or at least that is the obvious error that your.. 'error' is telling me...
(this may be because, as Helios stated, it has been depreciated, and your compiler has maybe stopped supporting/supplying it)

Use <iostream> instead, and use int main() versus void main().
You should end with a 'return 0;' as well. Like so:

Code: [Select]

#include <iostream>
using namepsace std;


int main()
{
...
return 0;
}

Re: Get an error when I try to compile this(C++)

and use main(), not void main().

you probably mean "int main()" and then he need to (or may?) end the main-function with "return 0;" too.

My signature is empty.

Yes, and yes...

Re: Get an error when I try to compile this(C++)

It's as helios said. If you had cross checked with other code, you would have seen that they use <iostream>, not <iostream.h>.

the void main probably isn't a problem, although int is used more these days so that you can return the success or failure of your program.

Re: Get an error when I try to compile this(C++)

So I changed what you people suggested but now I get 3 errors the source code is now.

Code: [Select]

//Oefening1: Klassen en objecten
#include <iostream>

//De klassendeclaratie
class Breuk
{
private:
int teller,noemer;//Klasse-variablen

public:

};

//De klassedefinitie
int Breuk::Ingeven()
{
cout<<endl<<"Geef de waarden van teller en noemer:";
cin>>teller>>noemer;
}

int Breuk::Tonen()
{
cout<<endl<<"De breuk is :"<<teller<<"/"<<noemer<<endl;
}

//Het hoofdprogramma
int main()
{
Breuk B1;
B1.Ingeven();
B1.Tonen();
return 0;
}The errors

You need to declare the namespace you wish to use. Put 'using namespace std' below your include statements..

Re: Get an error when I try to compile this(C++)

You need to learn to debug things yourself, as around 80% of programming tends to be debugging and with that amount of debugging you can't expect to ask other people to solve the problems for you. This error is fairly simple to understand, let me explain it.

c:\documents and settings\hyrule_boy\c++\oefingen\visual c++ boek\oefening1\oefening1\oefening1.cpp(7) : error C2143: syntax error : missing ';' before '<class-head>'

That is the file the error occured in.

c:\documents and settings\hyrule_boy\c++\oefingen\visual c++ boek\oefening1\oefening1\oefening1.cpp(7) : error C2143: syntax error : missing ';' before '<class-head>'

That is the line the error occured on.

c:\documents and settings\hyrule_boy\c++\oefingen\visual c++ boek\oefening1\oefening1\oefening1.cpp(7) : error C2143: syntax error : missing ';' before '<class-head>'

This is the internal error code, you can use google to get more detailed infomation about the error by using this code.

c:\documents and settings\hyrule_boy\c++\oefingen\visual c++ boek\oefening1\oefening1\oefening1.cpp(7) : error C2143: syntax error : missing ';' before '<class-head>'

This is the error discription it explains how the error was caused, in this case its because there is a missing semi colon.

I do not expect that people here solve my problem. I made this code from a book I bought. And I checked several times if I typed it good. And I don't see what I did wrong.

It's because the books are old.

It's as helios said. If you had cross checked with other code, you would have seen that they use <iostream>, not <iostream.h>.

the void main probably isn't a problem, although int is used more these days so that you can return the success or failure of your program.

it's "int main". Everything else is not following the standard. By not following the standard you can't guarantee that the code will compile on any compiler on any system.

My signature is empty.

There is no <class-head> in the source code.

Re: Get an error when I try to compile this(C++)

Check your code for any syntax errors. There is something wrong with it. No offense, but this is a very simple program, and you have to learn to debug for yourself. If you ever want to do anything with your code [like direct x, networking, opengl, windows programming, classes, etc.] you have to learn to look for your own bugs.

Seriously, I've literally spent hours trying to solve a single bug before. It's part of the programming experience. You have to learn to figure out what's wrong on your own.

I know this is a simple program its the first lession in the book I only typed what stand there. And Bongo Bob the latest version is at the bottom of page 1.

EDIT: THIS IS EXTREMELY WEIRD!!! When I used this code

Code: [Select]

//Oefening1: Klassen en objecten
#include <iostream.h>

//De klassendeclaratie
class Breuk
{
private:
int teller,noemer;//Klasse-variablen

public:
void Ingeven();//Methoden
void Tonen();
};

//De klassedefinitie
void Breuk::Ingeven()
{
cout<<endl<<"Geef de waarden van teller en noemer:";
cin>>teller>>noemer;
}

void Breuk::Tonen()
{
cout<<endl<<"De breuk is :"<<teller<<"/"<<noemer<<endl;
}

//Het hoofdprogramma
int main()
{
Breuk B1;
B1.Ingeven();
B1.Tonen();
return 0;
}
It works fine in Dev-C++ but when I try to compile it in Microsoft Visual C++ 2005 proffesional edition I get errors. O____O

Are you sure you are not compiling under .NET, (VC++ 2005 can compile both native and IL executable images), as .NET has some quite significant changes.
