What is your preferred boolean pair: 1/0 Yes/No True/False?

Question

1. When dealing with MySQL, I typically use the BOOLEAN type, which is equivalent to TINYINT(1), or 1/0
2. In most languages I work with, true/false is preferred
3. When displaying forms, sometimes "Yes / No" makes more sense

Answer 1

enum Bool 
{ 
    True, 
    False, 
    FileNotFound 
};
