Solution 2

cout is defined by <iostream> inside the std namespace.

You can either do

...
std::cout << "your text" << std::endl;
...

or

...
using namespace std;
...
cout << "your text" << std::endl;
...

Solution 1

you need to either explicitly scope cout from namespace std, or scope the namespace entirely. std::cout will work. I believe it's using namespace std; but I'm so long out of C++, that could be wrong.
