The void data type is used to hold any type of variable, provided that it should be typecasted.
Here the void variable is holding int value and it's not declared/typecasted hence the compiler doesn't know what type it is and hence it raises an error.

Every variable needs storage in memory for storing values. Here Datatype in null, means it will not store any value. Thank you.

Void is not a keyword, it is a datatype.

void is a datatype but the compiler does not allocate memory for that one.
The sizeof(void) it gives 1 byte.but memory not allocated so variable not declared with void.

Hi friends, in my view, the void is a primary data type and it (void) means no return value.

@All.
You cannot declare a variable of type void.

Actually, In this program, variable we is defined with void, at the time of compiling compiler will not able to allocated memory for that variable, because datatype of variable we is not given, so, error is thrown by compiler.
Thank you.
Thank you.

Here, the void is in pointer when we use void, convert (typecasting) into a desired data type.

As per my knowledge; It is
#include<stdio.h>
int main()
{
void v = 0;
printf("%d", v);//* the address is not allocated so it's a very easy but somewhat difficult to crack ok *//
return 0;
}
