Is void a data type in C?


a data type in the C programming language? If so, what type of values can it store? If we have
, etc., to store values, why is

Answer Source

Void is considered a data type (for organizational purposes), but it is basically a keyword to use as a placeholder where you would put a data type, to represent "no data".

Hence, you can declare a routine which does not return a value as:

void MyRoutine();

But, you cannot declare a variable like this:

void bad_variable;

However, when used as a pointer, then it has a different meaning:

void* vague_pointer;

This declares a pointer, but without specifying which data type it is pointing to.
