    I think the answer is simply
    void* p;

    malloc is just the library function called to allocated some memory and of course a void pointer will be returned , but it is the declaration of a void pointer.

    Ofcourse declaring a void pointer means void* var;
    we will use malloc to assign memory to var before using it ie before assigning it a value of any type.

    Better is to use void *p.
    Even you can associate the * or & to the type instead of the variable like void* p; But this may lead to a confusion when you go for this kind of declaration void* p, q.
    By looking at this you may think q is also a void pointer but it is not so it becomes a ordinary variable.

    To raushan:

    we can declare a pointer of type void,but we cant declare a variable of type void bcoz datatype void doesnt exist.
