It is char *, not a std::string.

>From docs:

Boolean conversions

Prvalues of integral, floating-point, unscoped enumeration, pointer, and 
pointer-to-member types can be converted to prvalues of type bool.

The value zero (for integral, floating-point, and unscoped enumeration) and the 
null pointer and the null pointer-to-member values become false. All other 
values become true.
