A language that supports the statement construct typically has rules for one or more of the following aspects: Statement terminator – marks the end of a statement; Statement separator – demarcates the boundary between two statements; need needed for the last statement; Line continuation – escapes a newline to continue a statement on the ...
In logic, negation, also called the logical not or logical complement, is an operation that takes a proposition to another proposition "not ", written , , ′ [1] or ¯. [citation needed] It is interpreted intuitively as being true when is false, and false when is true.
In Boolean logic, logical NOR, [1] non-disjunction, or joint denial [1] is a truth-functional operator which produces a result that is the negation of logical or.That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both p and q are false.
The stable model semantics define a condition for calling certain Herbrand models of a program stable. Intuitively, stable models are the "possible sets of beliefs that a rational agent might hold, given [the program]" as premises. [11] A program with negation may have many stable models or no stable models. For instance, the program
In Java, % is the remainder operator , and in Java, if its first operand is negative, the result can also be negative (unlike the modulo used in mathematics). Here, the programmer has assumed that total is non-negative, so that the remainder of a division with 2 will always be 0 or 1.
In computing, compiler correctness is the branch of computer science that deals with trying to show that a compiler behaves according to its language specification. [citation needed] Techniques include developing the compiler using formal methods and using rigorous testing (often called compiler validation) on an existing compiler.
A definition or declaration specifies the data on which a program is to operate, while a statement specifies the actions to be taken with that data. Statements which cannot contain other statements are simple; those which can contain other statements are compound. [2]
When performed on a negative value in a signed type, the result is technically implementation-defined (compiler dependent), [5] however most compilers will perform an arithmetic shift, causing the blank to be filled with the set sign bit of the left operand. Right shift can be used to divide a bit pattern by 2 as shown:
