"Void" is no return type keyword for function use, not use in variable declaration.

void doesn't return anything so instead of void if int is declared we get the result as 0.

If a variable is void and when it is printed with any datatype it accept the size and data type. So how it is wrong?

Hello, all.
We can not assign the value of the pointer.
but void *p;p=0;
int *i;i=0; is valid but p=1, p=9, p=67 and i=12, i=4 is not valid why?

The void is not a data type (both primitive and non-primitive), so declaring variable 'v' with void data type leads to giving an error.

We never use void for declaration variables because void means nothing, so if we used void in the variable that means no variable existing and this not related to c language. But we use void in function argument declaration.
