Q1. What happens when you use a copy constructor in C++
Ans. 
Using a copy constructor in C++ creates a new object by copying the values of another object.
• Copy constructor is a special member function that creates a new object as a copy of an existing object.

• It is invoked when a new object is created from an existing object.

• Example: MyClass obj1; MyClass obj2 = obj1; // Copy constructor is called to create obj2 as a copy of obj1.

Q2. When to use pointer/reference
Ans. 
Pointers/references are used to pass memory addresses instead of values, for efficiency and to modify data directly.
• Use pointers when you need to modify the original data passed to a function

• Use references when you want to avoid copying large data structures

• Pointers are commonly used in dynamic memory allocation

• References are used in function parameters to avoid unnecessary copying

• Example: int x = 10; int *ptr = &x; *p
