What Is the Purpose of the Void Pointer in C?

Introduction

Void pointers, also known as generic pointers, are a powerful feature in C that allow pointing to any data type…

Definition

A void pointer is declared as:

void *ptr;

Usage

Void pointers are often used for generic functions like memory allocation or type-agnostic data handling. Example:

int x = 10;
void *ptr = &x;
printf("Value: %d", *(int *)ptr);

Limitations

Void pointers cannot be dereferenced directly without casting. This makes them versatile but requires careful handling.
