copy constructor c++ syntax

Here is the syntax for a copy constructor in C++ along with explanations for each step:

class MyClass {
public:
    int data;

    // Copy constructor
    MyClass(const MyClass &obj) {
        data = obj.data;
    }
};

Explanation:

1. MyClass is the name of the class for which the copy constructor is being defined.
2. public: indicates that the members following it are accessible to all.
3. int data; declares an integer variable called data.
4. MyClass(const MyClass &obj) is the copy constructor declaration. It takes a reference to an object of the same class as a parameter.
5. data = obj.data; is the assignment statement copying the value of data from the object obj to the current object.
