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
What is the difference between BOOL and bool? - Stack Overflow The values for a bool are true and false, whereas for BOOL you can use any int value, though TRUE and FALSE macros are defined in the windef h header This means that the sizeof operator will yield 1 for bool (the standard states, though, that the size of bool is implementation defined), and 4 for BOOL
boolean - What is bool in C++? - Stack Overflow Bool is a well-defined primitive integral type, just like int, char, etc It also has mathematical conversions to other integral types, which can sometimes be confusing for people, but I don't think that is the source of your current confusion
What is the difference between bool and Boolean types in C# 2 bool is a primitive type, meaning that the value (true false in this case) is stored directly in the variable Boolean is an object A variable of type Boolean stores a reference to a Boolean object The only real difference is storage
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,
Using Boolean values in C - Stack Overflow bool and _Bool, and true and false are language keywords for boolean types bool _Bool is a type that can hold either the value true or false Logical operators !, ||, and can be used
Do the = and |= operators for bool short-circuit? - Stack Overflow bool allTrue = true; allTrue = allTrue check_foo(); allTrue = allTrue check_bar(); check_bar() will not be evaluated if check_foo() returned false This is called short-circuiting or short-circuit evaluation and is part of the lazy evaluation principle Does this work with the compound assignment operator =?
In c, in bool, true == 1 and false == 0? - Stack Overflow And that is why IMO the bool is of use only for setting a value, not testing For testing, it's inherent in the C langauge without any formal definition I'll go further: the bool type is completely useless except possibly to distiguish from those languages where true is -1, but the same applies: 0 is false, anything else is true
