How to call a child function with the same name as the parent (C++)?

Question

OOP

I recently started learning OOP. But here's something that can't be sorted out. Here is an example program code. How to make it so that the function of the child is called in the main, and not the parent?

class tparent
{
...
public:
...
  void getdata() 
  {
          ...
  }
};

class tchild:public tparent
{
...
public:
  void getdata()
  {
         ...
  }
};

void main()
{
       tchild ob;
       ob.getdata();
}

Answer 1

In your code, the child function will be called.
