Introduction to Algorithms/Variables

This is a lesson in in the course, Introduction to Algorithms, which is a part of The School of Computer Science

Objective

Variables In the above example it is fairly simple to follow the piece of toast through the algorithm, but if you imagine that the algorithm could become more complex, and thus the progress of the toast much harder to follow. In order that, at any point in the algorithm, it is clear what is being talked about, names are often given to things. For example Algorithm for making buttered toast (3.0) LET A = a loaf of bread LET T = a toaster LET P = a plate LET B = some butter LET S = cut slice from A get A move the S to T turn on T wait for T move the S to P spread S with B
