C++ calling base class constructors

Question

#include 
#include  
using namespace std;

// Base class
class Shape 
{
   public:
      void setWidth(int w)
      {
         width =         


        

Answer 1

The default class constructor is called unless you explicitly call another constructor in the derived class. the language specifies this.

Rectangle(int h,int w):
   Shape(h,w)
  {...}

Will call the other base class constructor.
