Question

What is the advantage of a void pointer in C?

Answer 1

There are following advantages of a void pointer in c.

• Using the void pointer we can create a generic function that can take arguments of any data type. The memcpy and memmove library function are the best examples of the generic function, using these functions we can copy the data from the source to destination.
• We know that void pointer can be converted to another data type that is the reason malloc, calloc or realloc library function return void *. Due to the void * these functions are used to allocate memory to any data type.
• Using the void * we can create a generic linked list..
