We cannot declare a variable with void as data type.

Because void is not a datatype. So syntaticaly its violates the declaration of a variable. So it raises compile time error.

We must first convert it into desire data type before using it.

Only pointer can be void not a variable.

For declaration of any variable required datatype variable
That is
Ex int v=0;
void is a return type not a datatype,
Therefore in this program, void v=0;.
Generates an error.

Void returns only zero.
We cannot use it like data type only use return type.

Void is an generic pointer which contain any type of data. But it's size is unknown value. Before assign the void pointer value you must type converted into the required one.
void v;
int b;
b=(int)v;
void v;
int b;
b=(int)v;

Data type should be of int or one can use typedef function.
