Students code the following questions, as they will help you in upcoming graded lab.

Code:

Q1. Replace following constructors with a single constructor.
   class food{
      char * color;
      char *name;
      int weight;
      float price;
      food (){}
      food (){
         color = NULL;
         name = NULL;
         weight = 5;
         price = 0.5;
      }
      food (char *Color, char *Name, int Weight, float Price){   
         color = Color;
         name = Name;
         weight = Weight;
         price = Price;
      }

      food (char *Color = "red", char *Name = "Apple", int Weight = 5, float Price = 0.5){
         color = Color;
         name = Name;
         weight = Weight;
         price = Price;
}
   
   }

Q2. Write a copy constructor which will copy all contents of one object to another.
   class Obj{
      int *abc;
      char *xyz;
      Obj (Obj object){} // Write it twice one for shallow copy and one for deep copy.
   }

   Help: See your lecture slides.
Q3. Write a getter function which will return the current object.
   class Student{
      int rollno;
      char *name;
      Student getStudent (){}
   }
