Best Answer

You overload a constructor by declaring two or more constructors in a class, each with different signatures.

When no constructor is specified, a default constructor and a copy constructor are implied. Both can be overridden. The default constructor can also be overloaded if all arguments are given default values in the declaration.

You can add as many construction overloads as required in order to initialise your class. If your class has many members to initialise, it may be helpful to use a structure and an overloaded constructor to accept the structure.

For every constructor that has exactly one argument, there should also be an equivalent assignment operator overload. The copy constructor assignment overload is implied if not specified.

What is constructor overloading in c plus plus?

Constructor overloading, just like any function's overloading, is where more than one configuration of parameters exists for the function. Based on the number and type of the parameters, different versions of the function can be resolved by the linker. This is typically used in the constructor as the default constructor (no parameters), the copy constructor (one reference parameter of the same type as the class), and the conversion constructor (any other combination of parameters).

Which key word is used as constructor in c plus plus?

There is no specific keyword for a constructor in C++. Simply define and declare a method of the class with the same name as the class and it will be a constructor. A constructor with no arguments is the default constructor, a constructor with one argument of class type is the copy constructor, and a constructor with one argument of some other type is the conversion constructor. You can provide other overloaded constructors if you want.


What is dynamic constructor in c plus plus?

What is the difference between constructor and destructor in c plus plus?

The constructor is a method that runs to initialize the instance of the class. It runs right after memory allocation. The destructor is a method that runs to deinitialize the instance of the class. If runs right before memory deallocation.


Can you write own constructor in c plus plus?

Yes.


What is the Difference between Method overloading and method overriding in C plus plus?

Overloading a method means to provide the same method name with different signatures, to cater for all the different parameter types that may be passed to a method. Overriding means to provide a new implementation of an existing method, inherited from a base class. Overloaded methods can also be overridden.

What is the difference between implicit and explicit call of constructor in c plus plus?

An implicit constructor call will always call the default constructor, whereas explicit constructor calls allow to chose the best constructor and passing of arguments into the constructor.


What is the difference between constructor and friend function in c plus plus?

A constructor is a method that fires when the object is instantiated. A friend function is a function that has special access to the object. They are two different types of things, and cannot be further differenced.
