In C++, you can provide the default values /arguments to the data members by using the default arguments while defining the constructor of the class.Problem statementWrite a C++ program to create a constructor with default arguments.Steps to create a constructor with default arguments...
A parameterized constructor with default arguments is a constructor, which allows a user to provide default values for one or more parameters, which means you can either pass values while creating the object or let the constructor use the default values for the missing parameters.Syntax...

Explanation Here, MyClass() is the default constructor, where initializing a and b to 0. MyClass(int x) is the constructor with one argument, where initializing a and b to x and 0 respectively. MyClass(int x, int y) is the constructor with two arguments, where initializing both a and...
In this post, we are going to learn parameterized constructor in C++ programming.What is Parameterized Constructor in C++?As the name suggests it's a constructor with arguments/parameters, it follows all properties of the constructor and takes parameters to initialize the data....

Can there be more than one destructor in a class?No, there can only one destructor in a class with classname preceded by ~, no parameters and no return type.When do we need to write a user-defined destructor?If we do not write our own destructor in class, compiler creates a default ...
declare a static constructor, which initializes static members of the type. Static constructors are parameterless. If you don't provide a static constructor to initialize static fields, the C# compiler initializes static fields to their default value as listed in theDefault values of C# types...
