1. Size of 'v' is unknown or zero
2. Value of type is not allowed in this statement- printf("%d",v);

Void means which not return any thing. If you put void in front of main function means that is not return any thing.
So, void should not be used for declaring the variable data types otherwise it shows error.

void is a primary data type. We are using variable name of void type and intialized as zero then what is wrong in that?

You can never create a void variable. Only Creation of void pointer is possible.

v and *vptr is declared as void pointers and we cannot use v and *vptr until and unless we convert that variables to the desired data type.
Here we are assigning value 0 to v and v doent hold any memory location to assign the value first we have to convert void v to integer type then only we can assing the value to it.
Ex (int) v = 0 ;
or v = (int) 0 ;
Anything I am not sure.

Is the question correct?
BOth the pointers point to v ?
cptr = &v;
vptr = &v;
Or is it
cptr = &c?
