[B]Overloading Functions In Inheritance[/B]

Hi Folks,

My understanding is that to overload functions across class, the base class's function must be declared in the derived class and then it would allow me to overload a function. But the below code is not compiling. Any help in this direction would be appreciated.

Code:

#include <iostream>
using namespace std;

class A
{
      public:
             void hello(int i);
};

class B : public A
{
      public:
             void A::hello(int);
             void hello(char *ch);
      
             
};

void A::hello(int i)
{
     cout << "Value of int is i " << i << endl;
}
void B::hello(char *ch)
{
     cout << "Value of char is " << *ch << endl;
}
int main()
{
    B b1;
    b1.hello((int) 10);
    char ch = 'A';
    b1.hello((char*) &ch);   
    return 0;
}

Hi Guys,

Recollected the concept. Here's the solution

Instead of coding
void A::hello(int) // in class B,
I should have typed
using A::hello;

Why do you cast the value of things when you are passing them to your functions this is not needed.

Code:

#include <iostream>

class A
{
    public:
        void hello(int i);
};

class B : public A
{
    public:
        void hello(char *ch);
};

void B::hello(char *ch)
{
    std::cout<<ch<<std::endl;
}

void A::hello(int i)
{
    std::cout<<"I = "<<i<<std::endl;
}

int main()
{
    B b1;
    char ch = 'h';
    
    b1.hello(10);
    b1.hello(&ch);
    
    std::cin.get();
    
    return 0;
}
