Hackerrank Accessing Inherited Functions Solution
You are given three classes A, B and C. All three classes implement their own version of func.
In class A, func multiplies the value passed as a parameter by :
class A
{
public:
A(){
callA = 0;
}
private:
int callA;
void inc(){
callA++;
}
protected:
void func(int & a)
{
a = a * 2;
