inheritance scope

[Gav]

hi,

could someone tell me why this program (which results in a compilation
error) shouldn't compile (i.e. is it a gcc thing or is it a strict part of
c++), and how i can make it compile without having to put C:: before foo()
in main()?

essentially i want the foo() from A to be overloaded as i would expect if it
was actually inserted into C.

thanks, gav

#include <iostream>
class A
{  public: void foo() { std::cerr << "A::foo(int)" << std::endl; }
};
class C : public A
{  public: void foo(int) { std::cerr << "C::foo(int)" << std::endl; }
} c;
int main()
{  c.foo();
   return 0;
}
