C Programming - Declarations and Initializations - Discussion

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

Only function and pointer can be declare as void not variable.

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.

What is the format specifier for 'void'?

Void is a primitive data type but it declaration of variable using void is wrong!thats it.

void means that it does not return nothing.Here void declare to the V is not taken.

We couldn't use &v in printf. We use that symbol for taking input from user in scanf statement not in printf statement.

void is a data type it can holds any type of data(int,float,char..)so, if u want to print void type of data need to type cast in to that stream .
printf("%d", v);

In this statement %d(int type)
So need to typecast in to integer like
printf("%d",(int)v);

The void type is said to comprise an empty set of values, and the C language does not provide any way to declare an object or represent a value with type void.
Thats why for the above problem the compiler shows the following:
Error: Declaration syntax error 'v' (or) Size of v is unknown or zero.

#include<stdio.h>
int main()
{
void v = 0;
/*C language does not provide any way to
declare an object or represent a value with type void*/

printf("%d", v);

return 0;
}

void can't be a data type, It is a return type which return null so it can't be declare with a variable name.

Ex: void a;// It show u an error.

Pointer variable declared as void. So it gives an error
