1. Default Constructor A default constructor is parameterless. If a class doesn't have a constructor then a default constructor gets called when object is created. The default constructor is added to a class by default if you don't add any constructor to your class. The default constructor sh...

If a type requires a parameter to create an instance, you can use aprimary constructorto indicate that one or more parameters are required to instantiate the type, as shown in the following example: C# publicclassLabelledContainer<T>(stringlabel) {publicstringLabel {get; } = label;publicrequ...
In addition to overloading constructors with different parameters, we can overload constructors with default parameter values, as well. For example: class Circle { private: double radius; public: Circle() { radius = 1.0; } Circle(double r) { radius = r; } Circle(double r, double x, ...
int b, c; public: ParamA (int b1, int c1) { b = b1; c = c1; } int getX () { return b; } int getY () { return c; } }; int main () { ParamA p1(10, 15); cout << "p1.b = " << p1. getX() << ", p1.c = " << p1.getY(); ...

A parameter default value ofnew()binds to the parameterless constructor if public (and reports an error that the value is not constant); otherwise the instance is zeroed.No change from C#9. C# // public struct PublicConstructor { public PublicConstructor() { } }// public struc...
If a class has no default constructor, an array of objects of that class cannot be constructed by using square-bracket syntax alone. For example, given the previous code block, an array of Boxes cannot be declared like this: c++ Box boxes[3];// compiler error C2512: no appropriate defaul...
