The 'void' keyword is represent no value but null pointer \0 or 0.
So () denotes the value * denotes address of memory location,
so (void*)0 is represent the NULL POINTER.

As we know pointer doesn't have any return type, we write the keywords like int, float or char before * when we create a pointer. These keyword show that which type of value's or variable's address pointer will keep. And here we can see that we have used void before * that means pointer will not point any memory location. And we know that pointer which doesn't point any memory location is called null pointer.

It is null pointer which is indicating a memory having nothing in it or void memory. But as it is pointer, it will store the address.

It refers null pointer. Because the return type void is mentioning the null (nothing). So it can be refered like this.

Pointers is I think the toughest topic I had ever came across about c. Can anybody please give some basics of pointer in simple language.

I think answer should be B, as void * shows that it is pointer to a data type, means it is a pointer to void data type, it will store the address of any data type.

I think void is the correct answer because void means no return type, but we know pointer should indicates address of the data type, but no return datatype are here. So (void*) indicates the NULL pointer.

Void means no return type and * means finding the address of return type. So that is represented as null pointer.
