The shallow copy can only be produced by the default copy constructor.

There are generally two types of the copies that are produced by the constructor:

Types of copies produced by the constructor Whenever the same class type object is generally returned by value by the function then the copy constructor is called.Whenever the same class type object is generally passed by value generally as an argument then the copy constructor is called.

The first case is when a object is initialized by the user with another existing object that is of the same type of class.These are the following scenarios when a copy constructor is called: Output :10 10 Copy Constructor is called when Student stu2(stu) //Calling the copy constructor. Student stu(10) //Here need to Call parameterized constructor. Student(Student &i) //This is copy constructor Student(int a)//This is parameterized constructor. Here is an example of the user-defined copy constructor for your better understanding: #include Here is the syntax of the user-defined copy constructor: Class_name(const class_name &old_object) User-Defined Constructor : This type of constructor is generally defined by the user or the programmer.Default Copy Constructor : The default copy constructor in C++ is defined by the compiler and the compiler also supplies the constructor if there is no copy constructor defined by the user.There are generally two types of the copy constructor in C++: An overloaded constructor that is used to initialize and declare an object from another object is known as a copy constructor in C++.
