Dear list,

I try to compile a hello world C++ program in FreeBSD 6.0, but get an
error as below:

[dm@ORION ~/cpp]% CC -o hello hello.C
hello.C: In function `int main()':
hello.C:5: error: `cout' undeclared (first use this function)
hello.C:5: error: (Each undeclared identifier is reported only once
for each function it appears in.)
hello.C:5: error: `endl' undeclared (first use this function)

I noticed that "iostream" file is located in
"/usr/include/c++/3.4/iostream", I guess my CC compiler cannot find
this head file. Is it true? And how can I fix this problem? Your
advice is appreciated. Thanks in advance.

==quote of hello world code==
#include <iostream>

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

    return 0;
}
== end of quote==

Regards,
David

Also, noticed your code is flawed, you never used a namespace, nor explicitly
stated one. cout is part of the 'std' namespace, so either ' using namespace
std;' for global/local use of namespace, OR do 'std::cout <<' instead. Try the
hello.cpp I sent you in the last email, that one should work for ya :)

Nathan,

I'm learning c++ programming language by using "The complete c++
training course - second edition" (Harvey Deitel & Paul Deitel), hello
world is the first program in this book.  I'm totally puzzled by this
complex language when I compile my first program. Is this book out of
date?


No, Deitel and Deitel isn't too bad. If you are new to programming in
general, I highly recommned "C++ : A Dialog", by Steve Heller.  He gradually
takes someone along to learn programming with C++. In fact, the full text is
available on his web site:

UNIX is user-friendly. It's just a bit picky about who its friends are.
