How is cout invalid?

[dingdong]

Like my name? It suits me pretty well. Especially with this stupid error:

#include <iostream>
#include <stdio.h>

int main()
{
cout << "Hello\n";
return 0;
}

I'm using Bloodshed Dev-C++ 4.9.9.2.
Am I using a deprecated #include? Here's my error:
"`cout' undeclared (first use this function)"

How am I supposed to use C++ if COUT is giving me an error?

[Bazzy]

it is std::cout, so add std:: before cout or the line using namespace std; after #includes

Thanks so much!

normally using std::cout; will do just fine.
