09 - Compound Functions (Part 1)
Functional programming languages chain functions together - and this can get complicated. But there is a trick - do it slowly. Here are the steps:-
1) Create an example.
2) Work throgh solving that problem ONE step at a time and keep track of the output you expect.
3) Take your worked example and create that in Scheme checking each step as you go. Run and test each step. Do you get the output you expected?
4) Find a way to check whether the final answer really is correct.
At the end of the video you were asked to create a function in Scheme to Fahrenheit into centigrade and maybe you were expecting to find the answer here - that would be pointless. However, I can tell you how to check your answer. Use 68F as your test case and you should get 20 as the output.
