Void is the data type used to declare pointer type variables but not the ordinary varibles..
eg
void *p; //correct
void p//not applicable
eg
void *p; //correct
void p//not applicable

We cant declare variable as a void in c..........It is valid for function.......IF WE use pointer then we can use (void*) as a datatype known as generic pointer....

We cannot create simple variable as a void because void means nothing.

One should not declare as the datatype because the void data type can be used for pointer variables.

Void is not a datatype.
It is a keyword.

Void can be used as int, char so what is the error in the above program.

void datatype wont allocate any memory so if void type means nothing but void* makes sense when sending generic type of data to functions and they act like generic pointers which can be converted to other types..

void is a return type and variable should not declare to it.
