When should I use void pointers in C?

What are void pointers and when should I use them?

Void pointers are pointers that can point to any data type. You should use them when you need a generic pointer type.

Can you give me an example of using a void pointer?

Sure! You can use a void pointer in a function that accepts different data types, like this: void printValue(void *ptr, char type) { ... }.

Are there any downsides to using void pointers?

Yes, void pointers can lead to type safety issues since they don't have a specific type. You need to cast them back to the correct type before use.

When should I avoid using void pointers?

Avoid using void pointers when type safety is crucial, or when you can use templates or generics instead.
