Re: [Dev-C++] The & in a conditional statement.

[<cg...@wo...>]

It's performing the logical AND operation with m_afConditions and 
iConditions, if the result is different from zero (true) return true, 
else return false. (Notice that would be shorter do [...]{return 
m_afConditions & iConditions;})
To be true at least one of the bits which is set in m_afConditions has 
to be in iConditions.
AND true table:
1 AND (&) 1 = 1 (true)
1 AND (&) 0 = 0 (false)
0 AND (&) 1 = 0 (false)
0 AND (&) 0 = 0 (false)
