AskDefine | Define postcondition

Extensive Definition

In computer programming, a postcondition is a condition or predicate that must always be true just after the execution of some section of code or after an operation in a formal specification. Postconditions are sometimes tested using assertions within the code itself. Often, postconditions are simply included in the documentation of the affected section of code.
For example: The result of a factorial is always an integer and greater than or equal to 1. So a program that calculates the factorial of an input number would have postconditions that the result after the calculation be an integer and that it be greater than or equal to 1.
postcondition in German: Nachbedingung (Informatik)
postcondition in Spanish: Postcondición
postcondition in Ukrainian: Післяумова (формальні методи)
