Why does a const int member in class produce error?

I have this const int private member in a class that produces an "uninitialized error" in the compiler for some reason, and I don't know why. At first I thought it was because I didn't assign it a value in the constructor, but then I added the code to do that, and it still gives the same error.

Any ideas?

A const member (or variable) cannot be assigned values.

You have to initialize it inline (in which case it must be static)

Code:

---

private:
    static const int A = 5;

---

Or in an initialization list.

Thanks, that worked.

Code:

---

class foo
{
public:
    foo(): m_foo(0) {}
protected:
    const int m_foo;
};
