Conditional (computer programming)
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 functional programming, a conditional expression does not have side-effects, many functional programming languages with conditional expressions (such as Lisp) support side-effects.
