simple c++ compile problem

[turbine]

Howdy all:

I tried to compile this very simple c++ program using gcc and/or g++.
#include <iostream> // cout, cin

main()
{
char buf[255];

cout << "Please enter a string ==> "; // O/P to STDOUT (screen).
cin >> buf; // I/P from STDIN (keyboard).
cout << "Entered string is " << buf << endl;
}

I get an error saying that cin and cout are not defined. I've tried this on both knoppix 3.3 and knoppix 3.7.

Any ideas?

You're using functions (cout, cin) from the standard library but you haven't told the compiler. Add the line "using namespace std;" after your include line. Or preface all your cout/cin/endl etc with std::. This is a basic C++ question, nothing to do with Knoppix etc. You code wouldn't compile on any standard compiler.

Thanks for the info, markb, I'll give your suggestion a try. Even though it wouldn't compile on any standard compiler, I forgot to mention, it compiled and ran just fine with both gcc and g++ on a Debian Woody installation.
