Where is iostream.h ?

[minthaka]

I'm doing my first steps in C++, bought a book called C++ for Linux, but I have problems in the very first progtam the "Hello world!". Of course I wanted to compile it with gcc try.c -o try , but it answered me it cannot find iostream.h included in the source code. I'm using gcc-4.1. What's wrong ?

Post your code. Did you remember to add using namespace std; at the top right after your header declarations?

[minthaka]

#include <iostream.h>;
using namespace std;
int main(){
cout << "Hello world !\n";
return 0;
}

ERROR>
Try.c:1:23: error: iostream.h: No such file or directory

[techieMoe]

#include <iostream.h>;
using namespace std;
int main(){
cout << "Hello world !\n";
return 0;
}

ERROR>
Try.c:1:23: error: iostream.h: No such file or directory

You need to decide whether you want to write this in C or C++. You're mixing two different coding styles and compiling it with gcc. In ANSI standard C++, you do not put the .h after your header declarations. Also, cout is a C++ statement that will not be understood by the gcc compiler. Here is what I would try:

#include <iostream>;
using namespace std;

int main(){
       cout << "Hello world !\n";
       return 0;
}

Save it as a .cpp file and compile it with this:

g++ try.cpp -o try

LOL

Easy mate.

Nobody has born knowing these tricks!!!!.

In a windows compiler, it would run perfect!!!!
but as you know windows is a !@(*&#!(@*&#(!@*#& dam place to improve programming skills!

This guy is starting good!!!! starting in POSIX life!!!!

completing...

#include <iostream>

using namespace std;

int main(){
       cout << "Hello world !\n";
       return 0;
}

DAMMM MAN!!! you must to decide wheter language you want to USE!!!!!

Save it as a .cpp file and compile it with this:

g++ try.cpp -o try

LOL
