No data type is there to 'v' here.
Void is not a data type to be assigned to any variable.

Void mean empty or NULL value. So void keyword cannot use variable declaration in C.

While initializing the variable requires a valid data type. void is return type not a data type.

Here declaration of a variable must be done by using predefined and user defined datatypes as void is also a predefined data type also we cannot use it here which it does not allocates any memory during declaration of variable.
ex: int a=0;
int i=0; these statements can be correct.

In printf statement how it is possible to print the value of 'v', hence we does not have to return anything using void data type, how it is possible to display the output.
This program will get syntax error.

What does a null ptr point to? If it is a ptr it should point to some location so is it that nothing is stored at that location?

Can not declare like this void is keyword it's not a datatype.

Only pointers can be declared as void not any other variable because pointers are of fixed size so even on being void its allocated space in memory but a normal variable declared as cannot be allocated space in memory and thus gives error.

Variable should not be a void type. It is not a valid type for variables.
We can only use it for functions.
Void in programming language means it does nothing.
