Conditional (computer programming)
open-in-new
<p>In <a href="/facts/Computer_science/lN3pEyPz">computer science</a>, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are <a href="/facts/Programming_language/cWTYbgWa">programming language</a> constructs that perform different computations or actions or return different values depending on the value of a <a href="/facts/Boolean_data_type/0GWYLDoC">Boolean</a> expression, called a <i>condition</i>. </p><p>Conditionals are typically implemented by selectively executing instructions. Although <a href="/facts/Dynamic_dispatch/211NC5eu">dynamic dispatch</a> is not usually classified as a conditional construct, it is another way to select between alternatives at <a href="/facts/Run_time_(program_lifecycle_phase)/lCxKsrzB">runtime</a>. </p>
