O_o cin and cout aren't declared?

Code:

---

#include <iostream>


int main()
{
    int aArray[12];
   
    cin >> aArray [4];
   
    cout << aArray [4];
   
    return 0;
}

---

Sorry if this is some really simple mistake, but I am just starting, (suppose it's obvious with the simplicity, but it was just to try it and see if I could get it to work,) but I thought iostream declared cin and cout?

Any help is really appreciated. Thanks.

std::cin, std::cout.

?

Never had to use std:: before. They've always worked straight away like that.

C++ Namespaces

You're probably used to a pre-standard compiler. The C++ standard introduced namespaces and placed every name in the standard library within the std namespace. Qualification is required on every compiler that claims to be standard.

Guess it makes sense. I hadn't used dev-c++ since I updated it.

Thanks again

(Sorry for the double post)
