Void

We've previously encountered void when we looked at functions that don't return anything or just display text on the screen.

Keep in mind that we can't declare a variable of the void type. However, we can create a void* pointer that points to a memory location.

Note

If you've worked through the pointer exercises in the section, you'll know that all pointers occupy 8 bytes. A void* pointer is no different.

A void* pointer isn't tied to any specific data type. This flexibility allows us to store the address of any data type in it.

However, there's a catch: we can't dereference a void* pointer.

Note

This limitation stems from the same reason we can't declare variables of the void type.

Perform an explicit type conversion!

Congratulations on completing the basic course in C programming! If you're eager to dive deeper into this fascinating and logical programming language, I highly recommend delving into topics like macros, sorting algorithms, and data structures. Additionally, familiarizing yourself with one of the Linux distributions is invaluable for any seasoned C programmer.

Best of luck!
