Re: [Newbie] Namespace and inheritance...

Hello,

I am learning C++. I wrote the following C++ code to understand
namespace and inheritance. It does not compile(g++ 4.6.3), but when I
explicitly specify the scope resolution the program works. Why am I
not able to directly call the public method implemented in the base
class?

namespace N1 {
     class C
     {
         public:
             void F(const std::string& s)
             {
                 std::cout << "N1::C::F(str): " << s.c_str() <<
std::endl;
             }
     };
};

namespace N2 {
     class C : public N1::C
     {
         public:
             void F(int i)
             {
                 std::cout << "N2::C::F(int): " << i << std::endl;
             }
     };
};

int main()
{
     N2::C c;
     c.F(1);

     // The following statement does not compile unless
     // it is called with full scope resolution as follows:
     // c.N1::C::F("one");

     c.F("one");

     return 0;
}
