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!
