Can't compile HW

[vcgeek]

I'm just beginning and I'm having trouble starting. Can't get this to
compile and could use some direction.

#include <iostream>
using namespace std;

int main () {
cout << "Hello World" << endl;
}

Here are the particulars:

Didn't think I'd need help this early.
TIA

Don't use gcc, use g++. Next time you have a problem using gcc or g++
please post to 'gnu.gcc.help' or 'gnu.g++.help'.

Thanks for g++ that appears to work. I had tried it earlier but must
have had some other problem. The doc sounds like either should work.

Also thanks for the correct group with out the flames.

#include <iostream>
using namespace std;

int main () {
cout << "Hello World" << endl;
}

First, I'd recommend changing that to:

#include <ostream>
#include <iostream>

using std::cout;
using std::endl;

int main()
{
cout << "Hello World" << endl;
}

gcc hw.cc

You're using the C compiler, not the C++ compiler.

Have you tried Dev-C++? I use it and it's pretty handy.

Either will compile the code. What g++ does for you is link the proper
libraries.

[ ... compiling C++ with: ]

gcc hw.cc

Try using "g++" instead of "gcc" and see it if doesn't help. Otherwise,
you're probably better off asking somewhere related to gcc rather than
C++. Here we discuss the language itself, not things like how to install
and use compilers (I know it sounds picky, but keep in mind that even
with the restricted range of topics, the volume here is already quite
high).
