Pass and store static function pointer in constructor

I have a class Foo.

class Foo
{
public:
    int(_bar)(const int);

    Foo(int(bar)(const int))
    {
        _bar = bar;
    }
};

I am trying to pass in a pointer to a static function on creation, and retain that in the class so I can call it later.

I am getting an error of...

error C2659: '=' : function as left operand

...but I don't understand why.

Can anyone please advise?

Function:

int(_bar)(const int);

Function pointer:

int(*_bar)(const int);

You just forgot the *
