The postcondition of a function

A) declares the function for the complier
B) determines how the function will complete its job
C) tells what will be true after the function executes.
D tells what must be true before the function executes

Answer 1

The post condition of a function is a statement that describes what will be true after the function executes.

Step-by-step explanation:

The post condition of a function is a statement that describes what will be true after the function executes. It is part of the function's documentation and is used to communicate to users of the function what they can expect as a result of calling it.

For example, let's say we have a function called calculated average that takes in an array of numbers and returns the average. The post condition of this function would be something like 'After calling calculated average with an array of numbers, the return value will be the average of those numbers'.

The post condition is important because it helps users understand how to use the function correctly and what they can expect as a result. It also helps with debugging and testing, as it provides a clear statement of what the function should do.
