The default constructor is always without parameters.
A Constructor with no argument is called default Constructor.
The default constructor can only be provided with named arguments.
A constructor with no arguments is called a default constructor.
The default constructor is called automatically, when an object of that class is created.
E479a Fix MSVC not properly zero-initializing values in the default constructor.
Added default constructor to OAuth1Parameters and OAuth2Parameters for more convenient standalone usage.
A constructor that takes no arguments is called a default constructor.
The default constructor is usually public(except for some very specific situations, where it is protected).
A constructor such as the one shown, that takes no arguments, is known as the default constructor. .
Although the default constructor and the one without parameters are similar in signature, they are completely different.
The observant reader has noticed that the so defined class has a default constructor, which is declared as private.
We should know that the default constructor is always named like the class, and its parameter list is always empty as well as its body.
If we declare at least one constructor in a given class,the compiler will not create a default constructor for us.
For example, you need to explicitly create a default constructor which takes no arguments to initialize the struct and its members.
We have to know that if we declare at least one constructor in a given class then the compiler will not create a default constructor.
Code that would go into the default constructor(other than initializing the member variables) goes directly at class level.
To make sure that the default constructor is always without parameters let's try to call the default constructor by setting it with parameters.
As we can guess,the only thing the default constructor will do when creating objects of our class, is to zero the fields of the class.
If the base class has no default constructor(one without parameters) or that constructor is hidden, our constructors need to explicitly call one of the other base class constructors. .
If the base class has no default constructor(one without parameters) or that constructor is hidden, our constructors need to explicitly call one of the other base class constructors. .
Moreover, as explained earlier, the default constructor will always have access level protected or public, depending on the access modifier of the class, while the level of access of the constructor without parameters all depends on us- we define it.
One way to solve this problem is to remove the default constructor(the one not taking any parameters) and to add one or more constructors, which take the sufficient data as their parameters, to enable the proper initialization of the object.

Initialization of the Fields in the Constructor As explained earlier when creating a new object and calling its constructor, a new memory is allocated for the non-static fields of the object of the class and they are initialized with the default values for their types(see the section"Calling a Constructor").
This constructor is called default implicit constructor and it will not have any parameters and will be empty(i.e. it will not do anything in addition to the default zeroing of the object fields).
We try to call a constructor without parameters in it,hoping that the compiler will have created a default parameterless constructor for us.
When we do not declare any constructor in a given class,the compiler will create one, known as a default implicit constructor.
Although we initialize the fields in the constructor, some people recommend explicitly assigning their type's default values during initialization with the purpose of improving the readability of the code, but it is a matter of personal choice.
The difference is that the default implicit constructor is created by the compiler, if we do not declare any constructor in our class, and the constructor without parameters is declared by us.
