Void is special kind of data type which is only built for functions return type (where no value is returned). So we cannot use this for any kind of variable declaration.

Void is a data type and we can use it at any time.

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

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;

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

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.
