In object oriented programming, a constructor is basically a function that is called when the object Is created. A destructor is called when the object is being destroyed (like going out of scope) class A { public: A() { std::cout << "A constructor called." << std::endl; } ~A(){ std::cout << "A destructor called." << std::endl; } void foo(){ std::cout << "foo called" << std::endl; } }; int main(){ A a; a.foo(); return 0; } This code will output: A constructor called. foo called A destructor called.

Working : Constructor is a special member function whose task is to initialise an object of it's class. & Destructor is a special member function whose task is to destroy the object created by constructor. Which gets called automatically when program ends.
