        In C language, an empty character constant is a character constant that has no characters between the single quotes. For example, '' is an empty character constant. 
        

        In C, a character constant is a sequence of characters enclosed in single quotes. An empty character constant is allowed in C, but it has no meaning or value. It is simply an empty sequence of characters.
        

        Empty character constants are not very useful in programming, but they are allowed by the C language standard.
