Pair as a member of a class

Hey there,
I am using Eclipse CDT on Linux (Ubuntu) and encountering a strange error.

This is my C++ header file:

Code:

class A {
public:
    A(int x, int y, bool direction);
    virtual ~A();

private:
    pair <int, int> m_pair_int;
    bool m_direction;
};

The implementation of the ctor and dtor is done at the cpp file and irrelevant in this post.

When compiling this code, I get the following error messages:
expected `;` before `<` token
ISO C++ forbids declaration of `pair` with no type
all these errors are pointing to the line where `pair <int, int> m_pair_int;` is.

Thanks in advance

Did you include the proper include file that defines pair?

Did you properly scope this standard class?

Jim

Also, given that putting using namespace std; inside a header file is a big no-no (bad practice), you'd better qualify pair with std::

Thank you both!!! I did miss these details (including utility and adding `std::` at the beginning of `pair`).
