In computer science, the Boolean (sometimes shortened to Bool) is a data type that has one of two possible values (usually denoted true and false) which is intended to represent the two truth values of logic and Boolean algebra. Boolean expression In computer science, a Boolean expression (also known as logical expression) is an expression used in programming languages that produces a Boolean value when evaluated. A Boolean value is either true or false. Operators in C and C++ This is a list of operators in the C and C++ programming languages. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading. The C language provides the four basic arithmetic type specifiers char, int, float and double (as well as the boolean type bool), and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. Both C (since C99) and C++ have a Boolean type bool with constants true and false, but they are defined differently. In C++, bool is a built-in type and a reserved keyword. C23 introduced the bool type as a core data type, while it was always a core data type of C++. C++ also features a std::byte type (similar to Java). C and C++ also contain size_t, intptr_t and other integer types, for things like indexing arrays and collections. These are not distinct data types, but often aliases and are system-defined. If-then-else flow diagram A nested if–then–else flow diagram In computer programming, a conditional statement directs program control flow based on the value of a condition; a Boolean expression. A conditional expression evaluates to a value without the side-effect of changing control flow. Many programming languages (such as C) have distinct conditional statements and expressions. In pure Short-circuit

evaluation, minimal evaluation, or McCarthy evaluation (after John McCarthy) is the semantics of some Boolean operators in some programming languages in which the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression: when the first argument of the AND function evaluates to false, the overall value must be
