Is constructor can return a value?
A constructor can not return a value because a constructor implicitly returns the reference ID of an object, and since a constructor is also a method and a method can’t return more than one values.
What happens if constructor has a return type?
Explanation: The constructor cannot have a return type. It should create and return new object. Hence it would give compilation error.
What is the return type of C constructors?
Constructors in C++ Constructor is a special member function of a class that initializes the object of the class. Constructor name is same as class name and it doesn’t have a return type.
Does constructor return any value in C++?
Constructor does not returns any value because constructor by default return a newly created instance and moreover you are not calling constructor specificlly it means the constructor automatically called when you creating the object so due to it called at the time of object creation it main responsibility is to …

A constructor doesn’t have any return type, not even void. A static constructor can not be a parametrized constructor. Within a class, you can create one static constructor only.
Can constructor return a value in C++?
Do constructors have return type in C++?

Why can’t I return a value from a constructor?
So the reason the constructor doesn’t return a value is because it’s not called directly by your code, it’s called by the memory allocation and object initialization code in the runtime. Its return value (if it actually has one when compiled down to machine code) is opaque to the user – therefore, you can’t specify it.
What is the return type of a constructor in C++?
Constructors don’t have return type. A constructor is automatically called when an object is created. If we do not specify a constructor, C++ compiler generates a default constructor for us (expects no parameters and has an empty body).

What is anconstructor in C++?
Constructors are functions that do not return a value. The family of functions that do not return a value consists of: void functions, constructors and destructors. It is stated in 6.6.3/2 in the C++ standard. The very same 6.6.3/2 states that it is illegal to use return with an argument in a function that does not return a value.
