Grandparent overloaded function in child
c++, overloading, overriding
Solution
The reason is method hiding.
When you declare a method with the same name in a derived class, base class methods with that name are hidden. The full signature doesn't matter (i.e. cv-qualifiers or argument list).
If you explicitly want to allow the call, you can use
using grandparent::foo;
inside `parent`.
Problem
I need to understand why C++ don't allow to access Grandparent overloaded functions in Child if any of the overloaded function is declared in Parent. Consider the following example: ``` class grandparent{ public: void foo(); void foo(int); void test(); }; class parent : public grandparent{ public: void foo(); }; class child : public parent{ public: child(){ //foo(1); //not accessible test(); //accessible } }; ``` Here, two functions foo() and foo(int) are overloaded functions in Grandparent. But foo(int) is not accessible since foo() is declared in Parent (doesn't matter if it declared is public or private or protected). However, test() is accessible, which is right as per OOP. I need to know the reason of this behavior.
