I feel a bit silly but somehow I seem to have forgotten a basic setting = in DEVC++. When I create a new project, using the templates for a console = application, I can compile and run without any problem. (Note: the = template contains the most simple main() with no functionality except = waiting for a keypress). Next when I add one line to main(): cout << "Hello world\n"; then compiling is ok but linking doesn't work anymore. I get the = message: [linker error] undefined reference to 'cout' Is there a library that I have to include? How does this work? |

Argh! :) can be overloaded? Exactly, the books I'm studying from are old, but I have seen references to omitting the header extension and using namespaces in (ANSI/ISO) C++. :)) Jim -----Original Message----- From: Ioannis Vranos > You mean :) must be used instead of ;-)?

Well i happened to start learning C++ with an outdated book too. I recommend to read "The C++ Programming Language" 3rd Edition or Special Edition by Bjarne Stroustrup (the creator of C++) after you finish with your introductory book(s). It will be much pain to read it cover to cover, but this is the cost of becoming an expert.

Thank you again. I have the 2nd edition of the book (1991) which does not cover namespaces, but recently purchased "Beginning Visual C++ 6" by Ivor Horton which is shaping up to be an excellent resource on both C++ and general Windows programming. Give me a few months and I'll not be such a C++ newbie.

C++ has become quite different since then.

You should learn about VC++ 7 .NET (that's what i am also learning this time). From the series of those books, i have the "Beginning Visual Basic 6" which is useless too (VB 7 .NET is quite different than 6).

This is my program: I still have the problem ([linker error] undefined
reference to 'cout')!
#include <iostream>
#include <stdlib.h>
using namespace std;
int main(int argc, char *argv[]) {
cout << "hello" << "\n";
system("PAUSE");
return 0;
}

I pasted your code into a blank file and compiled/executed it without
problem.

Your code is valid, you should not get any errors, although it could be
written better:
#include <iostream>
#include <cstdlib>
int main() {
using namespace std;
cout << "hello" << "\n";
system("PAUSE");
return 0;
}

Hello Ioannis and all Dev-C++ users,

Ain't that better to use cin.ignore() instead of cstdlib and

Yes that would be more portable.
