class Dual { public: int a; Dual(int x=0) { a = x; } }; int main() { Dual obj1; Dual obj2(10); } Here, in this program, a single Constructor definition will take care for both these object initializations. We don't need separate default and parameterized constructors. ...
Constructors CAN be declared in protected section of the class.class A {public: static A* Create(int x) { return new A(x); }protected: A(int x) { b = x; }private: int b;};A *a = A::Create(5); RE: Constructor and destructor - placement practice test -Atish Shriniwar (06/...

In the last paragraph of the section “A Look At the Calling Code” Mr. Sutter said (at a general level): “[…] we can say for all cases: The destructor/dispose is guaranteed to be run if and only if the constructor completed successfully.” ...
The pattern is the same for any class. You write a managed (__gc) class that holds a pointer to the native class, you write a constructor and destructor that allocate and destroy the instance, and you write wrapper methods that call the corresponding native C++ member functions. You don'...
Destructor: 1. It is a member function whose name is same as the class. But preceded by a ~ (tilde) symbol. 2. It has no return type. 3. It cannot have parameters. 4. It is implicitly called when object is no longer required. 5. It is used to release the memory and close file...
This means that an exception thrown from the body of a delegating constructor will cause the destructor to be invoked automati‐ cally. Example: class X { X( int, W ); Y y_; Z z_; public: X(); X( int ); X( W ); }; X::X( int i, W e ) : y_(i), z_(e) { /*...
