• Class Constructor:

  • Special member function of a class executed when creating new objects
  • Has the exact same name as the class
  • Does not have a return type
  • Useful for setting initial values for member variables
• Parameterized Constructor:

  • Can have parameters to assign initial values to an object at creation time
• Class Destructor:

  • Special member function of a class executed when an object goes out of scope or when the delete expression is applied to a pointer
  • Has the same name as the class prefixed with a tilde (~)
  • Does not return a value or take any parameters
  • Useful for releasing resources like closing files and releasing memories before exiting the program
