Why put void in params?

Question

What\'s the reason for putting void inside of the params?

Why not just leave it blank?

void createLevel(void);

void createLevel();

Answer 1

void in function argument lists is a relict of the past (C). In C++, you should leave the parentheses empty. Of course you can keep the void if it makes you happy.

In C, if you declare a function with empty parentheses, the meaning is that the number of parameters is unknown. void can be used to make it explicit that no parameters are expected.
