Default Constructors

• The purpose of a constructor is to initialize all data fields of an object.
• A constructor always has the same name as the class.

  Product::Product()
  {
     price = 0;
     score = 0;
  }
  

• Most default constructors initialize the data fields to zero, but not always.
  • The Time class initializes to current time.
  • Non-numeric data (e.g. string data) may have another value.
