- Q1. What is pointer
- Ans.
A pointer is a variable that stores the memory address of another variable.
Pointers are used to access and manipulate memory directly.
They are often used in programming languages like C and C++.
Example: int *ptr; // declares a pointer to an integer variable
- Q2. What is stack ?
- Ans.
Stack is a data structure that follows Last In First Out (LIFO) principle, used for storing temporary data in a program.
Stack is a linear data structure with two main operations: push (adds data) and pop (removes data).
Example: function call stack in programming languages like C, where function calls are added and removed in a LIFO manner.
Stack memory is used for local variables and function call management.

Register variables are stored in CPU registers for faster access.
Static variables have a lifetime throughout the program and are initialized only once.
Extern variables are declared outside of any functi...
