What is the difference between the following declarations?
void funct();
void funct(void);
I guess there is definitely a difference between them.

This is a function declaration. It indicates the name of the function
and the return type, but nothing about the type and number of
parameters (unspecified). It's usage is not recommended.

void funct(void);

This is a detached function prototype that indicates the name of the
function, the return type, and that the function accepts no parameters
at all.

void funct();

Declares a function which doesn't return anything,
does not specify what parameters it has.

void funct(void);

Declares a function which doesn't return anything,
specifies that it has no parameters.

Aside: In C++ the two are equivalent.
