What Is a Boolean Data Type? A boolean is a data type with two possible values:true (1) or false (0). The two values help represent truth conditions found in logic control structures. The name comes from a branc
Thus, if a data type is astring, the computer might interpret it as the name of a person or city, a greeting and so on. However, if the data is of typeBoolean, the computer will know that it can only have one of two values: true or false. Similarly, the computer will interpret w...
The size of theBoolean data typein C programming is not specified in the C standard, and it can vary depending on the implementation of the compiler and the architecture of the computer. However, in most implementations, theBoolean data typeis represented using one byte, which means that aBoo...
Boolean data type The term Boolean is sometimes presented with a lower case "b": boolean. Strictly speaking, Boolean with an uppercase "B" refers to Boolean logic or Boolean algebra, while boolean refers to adata typein computer programming. The other two major data types are text and number...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
A Boolean is a data type which has one of only two possible values: true or false. Booleans represent the truth values that are associated with the logic bra…

Learn about common data types—booleans, integers, strings, and more—and their importance in the context of gathering data.
A generic data type is a type that's defined in terms of other, partially unknown types. We've been using many generic data types since the beginning of this course, for example: TheOption<T>enum is generic over the typeT, which is the value contained by itsSomevariant. ...
