Answer / preeti
Constructor execution is depend on its type like,
1) inbuilt or default construtor, no parameter constructor
are executes whenever object creates.
2) parameterized constructor execute whenever it calls.
3) base class constructor execute before than child class
constructor(child class is derived from base class
constructor).

Constructor gets called when we create an object,or when we
allocated memory using new operator:

Why do we need oop?
1.explicit call for destructor 2.calling function inside a constructor. 3.base *b-new derived delete b; 4.delete p what it will delete. 5.size of base class and derived class int i,in base class and int j in derived. 6.int i-20 int main() { int i =5; printf("%d".::i); { int i =10; printf("%d".::i); } } 7.object slicing 8.new 9.function overloading(return type). 10.class base() { virtuval fun() { ----- } } class derivied:public base() { fun() { ----- } } int main() { derived d; } 11.how static function will call in C++? 12.default structures are in C++? 13.constructors should be in public . 14.virtuval constructor not exist. 15.multilevel inhritence. destructor order.
