Why is the c++ compiler in netbeans swearing at cout?

Question

C++ / C#

c++ compiler installed.
When writing code, he swears in netbeans on include (also tried with .h), cout (even on endl) and even attempts to bind printf there.
I also tried using std::cout.
What could be the problem? although it doesn't yell at the header math.h. But at the same time, it does not allow you to touch pow.

Answer 1

First - .h is C-headers, just all sorts of pluses
Second - I'm sure that you do not specify a namespace. Either specify at the beginning of the .cpp file using namespace std, or write

std::cout;
std::endl;

And in general - let's code.
