Step-by-Step Execution:

MyClass obj1(10);

The regular constructor is called with value = 10.
x is initialized with 10.
Output: Constructor called! Value: 10
MyClass obj2 = obj1;

The copy constructor is called with obj = obj1.
The value of x from obj1 (which is 10) is copied to obj2.
Output: Copy constructor called! Copied value: 10

/*
Yes, a copy constructor in C++ is responsible for creating a new object as a copy of an existing object. It performs a member-wise 
copy of the object's data members. If you have a simple object with non-pointer data members (like int, float, etc.), the default 
copy constructor provided by the compiler copies each data member's value.

What a Copy Constructor Does:
It copies all member variables of one object into another object of the same class.
The copied object is distinct from the original, but it holds the same values in its data members.
