Boolean is a type of data, with only two possible values: true and false.
bool has values True and False.
boolean has values true and false.
Almost every programming language has Booleans, because they’re necessary for the checks, comparisons and other logical conditions in if/else statements and loops.(1)
Computer programs use variables and data structures to store data in memory.(1) A data structure is a scheme for representing values of some type in memory; before we can understand, analyse and design data structures, we need to understand memory.
Using multiple bits to represent an integer requires deciding what the bits mean. A simple scheme for representing numbers could be to represent e.g. the integer value 3 by using three 1s, like so:
Programmers deal with many types of data: most programming languages have integers, booleans, floating point numbers, strings, lists, and more.
The word “type” has a specific meaning: each value has a type.
In Python the value 1 has the type int, and the value 'Hello, world!' has the type str.
In Java the value 1 has the type int, and the value "Hello, world!" has the type String.
