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

• 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
