C++ won't let me call a public method from a base class

Lets say I have 2 classes: foo and foo2 who are written as such:

foo.h:

#ifndef __InheritanceTest__foo__
#define __InheritanceTest__foo__

#include <stdio.h>
class foo
{
public:
    foo();
    int getSize();
protected:
    int size;

};
#endif

foo.cpp:

#include "foo.h"

foo::foo()
{
    size = 23;
}

int foo::getSize()
{
    return size;
}

foo2.h:

#ifndef __InheritanceTest__foo2__
#define __InheritanceTest__foo2__

#include <stdio.h>
#include "foo.h"
class foo2: foo
{
public:
    foo2();
};
#endif

foo2.cpp:

#include "foo2.h"

foo2::foo2()
{
    size = size *2;
}

this is my main:

#include <iostream>
#include "foo.h"
#include "foo2.h"

int main(int argc, const char * argv[]) {
    // insert code here...
    std::cout << "Hello, World!\n";
    foo2 f2;
    int i = f2.getSize();
    std::cout << i << "\n";

    return 0;
}

I'm getting two errors:

'getSize' is a private member of foo

and

cannot cast foo2 to its private base class foo.
