a null pointer points to nothing and a void pointer can point to anything.It can point to int or float or any data type.

void pointer is pointer that can store the address of any variable (float,int, pointer varaible).
But Null pointer is pointer that is used to denote the end of memory search and it doesnot point to any object or function or method.

void pointer - pointer is declared and defined its content as zero

null pointer - pointer is declared and not defined

Null pointer is a special reserved value of a pointer. A pointer of any type has such a reserved value. Formally, each specific pointer type (int *, char * etc.) has its own dedicated null-pointer value. Conceptually, when a pointer has that null value it is not pointing anywhere.

Void pointer is a specific pointer type - void * - a pointer that points to some data location in storage, which doesn't have any specific type.

So, once again, null pointer is a value, while void pointer is a type.

null pointer-null pointer points to nothing but initially its points to the base address of the segment of the memory.We cannot copy anythinf in the null pointer.
void pointer-void pointer is also called as universal pointer, it can be made to point to anything.
