Summary  
Pointers are variables that store memory addresses rather than direct values, which you obtain with the ampersand operator (&) and access or modify via the dereference operator (*). They enable direct manipulation of data in both stack-allocated variables and heap-allocated memory.

General domain of usage  
Dynamic data structures

A **pointer** in C is a variable that stores the **memory address** of another variable, allowing indirect access and modification of its value.

Definition

Pointers are a fundamental feature of C that allow you to work directly with memory addresses. Each variable in C is stored in memory, and its **address** represents the location where its value is kept.

Watch this video to see how pointers work in C, including how to declare, assign, and use them to access memory. You'll also learn about stack and heap memory, and how pointers enable dynamic memory management and efficient access to data.

Variables created inside functions are stored on the **stack**, which is automatically managed and cleared when the function ends. Memory allocated dynamically with functions like `malloc()` or `calloc()` comes from the **heap**, which you must manage manually using `free()`.

Pointers let you access and manipulate both stack and heap memory, making them essential for **dynamic data structures**, **efficient memory use**, and **low-level programming**.
