How do I use void pointers in C?

Void pointers in C are pointers that can point to any data type. They are declared using the keyword 'void'. How can I assist you further?

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

Sure! Here's a simple example:

void* ptr;
int num = 10;
ptr = # // ptr now points to an integer
printf("Value: %d", *(int*)ptr); // Cast to int* before dereferencing

What are the advantages of using void pointers?

Void pointers provide flexibility as they can point to any data type, making functions more generic. However, they require careful type casting.

Are there any downsides to using void pointers?

Yes, the main downside is that you lose type safety, which can lead to errors if not handled properly. Always ensure correct casting.
