Whats the difference between bool and bool?? bool is a value type, this means that it cannot be null, so the Nullable type basically allows you to wrap value types, and being able to assign null to them bool? can contain three different values: true, false and null
Difference between _Bool and bool types in C? - Stack Overflow These data types were added in C99 Since bool wasn't reserved prior to C99, they use the _Bool keyword (which was reserved) bool is an alias for _Bool if you include stdbool h Basically, including the stdbool h header is an indication that your code is OK with the identifier bool being 'reserved', i e that your code won't use it for its own purposes (similarly for the identifiers true and

boolean - Why is bool 8 bits long in C++? - Stack Overflow In C++, why is the bool type 8 bits long (on my system)? Only one bit is enough to hold the Boolean value I used to believe it was for performance reasons, but then on a 32 bits or 64 bits machine,
