I am reading C++ all in one desk reference for dummies. There is a lesson where you have to type the following:

CODE

#include <iostream>
#include <stdlib.h>

int main(int argc, char *argv[])
{
   cout << "Hello, I am your computer talking." << endl;
   system("PAUSE");
   return 0;
}

When I try to compile and run, I get an error message saying "cout" is undeclared.

Any suggestions?

Since you're just learning C++. Look at the section about Namespaces. All the Standard functions in the header files are inside a Namespace called 'std'.

In order to use the namespace you can use:

CODE
std::cout << "Hello, world!";


or...

you can type:

CODE
using namespace std;


after all your header file directives:

CODE

#include <iostream>
#include <cstdlib>
using namespace std;


That way the std namespace is being used by your program. That will allow you to keep the:

CODE
std::


off of all your functions.


Hope that helps,

Try putting

using namespace std;

Before your int main()

either that or you have to do std::cout instead of plain cout.
