Problem Statement - 02A-2016

Differentiate between Constructor and Destructor functions giving suitable example using a class in C++. When does each of them execute?


TC++ #6154


Constructor Destructor
A constructor function has same name as the class A destructor function has same name as the class preceded by ~ symbol
class Exam
  int Eno; float Marks;
  Exam()    //Constructor
    Eno=1; Marks = 100;
    cout<<”Constructor executed...”<<endl;
  void Show()
  ~Exam()    //Destructor
    cout<<”Exam Over”<<endl;
void main()
  Exam E;    //Executes constructor

Execution of Constructor and Destructor:

Constructor Destructor
A constructor executes by itself at the time of object creation A destructor executes by itself when the scope of an object ends
