Introduction to Pointers

Pointers are variables that store memory addresses instead of actual values.

In this lesson, you will learn:

• What pointers are and how they work.
• How to declare and initialize pointers.
• How to use pointers to access memory.

Declaring a Pointer

A pointer is declared using the * operator.

Example:

int *ptr;

This creates a pointer variable ptr that can store the address of an integer.
