compile error

[Das]

I am a newbee to c++. My first cpp is failing while compilation. I am executing it on Solaris.
My program:

#include <iostream>
using namespace std;
int main()
{
cout << "Hello\n";
}
~


Compilation and error:

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

Please let me know
1. what would went wrong
2. how to overcome
3. how to debug

[kbw]

You have two conlicting sets of header files, gcc headers and the system headers.

[Das]

so, which header you want me to remove? How to overcome the issue?

[rmccleave]

when using iostream library you use the endl keyword to skip lines

eg

cout<<"hi"<<endl;


\n is part of the stdio.h library

to use it you have to:

#include <stdio.h>

[kbw]

The code is ok, as far as it goes. You need to sort out your build environment, specifically your include and library paths.
