If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
An important use of the conditional operator is in allowing a single initialization statement, rather than multiple initialization statements. In many cases this also allows single assignment and for an identifier to be a constant. The simplest benefit is avoiding duplicating the variable name, as in Python:
the conditional operator can yield a L-value in C/C++ which can be assigned another value, but the vast majority of programmers consider this extremely poor style, if only because of the technique's obscurity. [6]
Any conditional statement consists of at least one sufficient condition and at least one necessary condition. In data analytics , necessity and sufficiency can refer to different causal logics, [ 7 ] where necessary condition analysis and qualitative comparative analysis can be used as analytical techniques for examining necessity and ...
Some languages have a functional form of an if statement, for instance Lisp's cond. Some languages have an operator form of an if statement, such as C's ternary operator. Perl supplements a C-style if with when and unless. Smalltalk uses ifTrue and ifFalse messages to implement conditionals, rather than any fundamental language construct.
All logical operators exist in C and C++ and can be overloaded in C++, albeit the overloading of the logical AND and logical OR is discouraged, because as overloaded operators they behave as ordinary function calls, which means that both of their operands are evaluated, so they lose their well-used and expected short-circuit evaluation property ...
Conditional approval usually means that you almost have a home loan — but you need to take certain steps (e.g., meet the stipulated conditions) to finalize it.
Multiway branch is the change to a program's control flow based upon a value matching a selected criteria. It is a form of conditional statement.A multiway branch is often the most efficient method of passing control to one of a set of program labels, especially if an index has been created beforehand from the raw data.
