What's the difference between pseudocode and algorithm?

Question

is there any differences between the pseudocode for a program and the algorithm for a program?
What are they?
if no, why?

Answer 1

They aren't the same thing in any way. You could just as well ask "What's the difference between an assay about cars and a car?" You couldn't quite name differences, because there weren't any similarities to begin with.

An algorithm is kind of a recipe for solving a task in a determined manner. It's the abstract idea of performing certain (maybe conditional) steps, to arrive at a goal.

Pseudocode is a syntax to describe the flow of a program or process. As such, it *can* describe algorithms. But the pseudocode is in no case the algorithm, as describing something isn't being that something. Just as an assay about cars isn't a car (or anything near a car), even tho it might describe one or more cars.
