I only found out your RUclips channel two days ago and I have watched the wjec playlist and you're a hero. I have learnt so much from you than from my teacher over the year. I think computer science is a subject many teachers struggle to teach. Only two days till my exam and I wish I knew about this channel before.

thank you for making this easy to understand! Was having a hard time understanding how to use pseudocode and i feel a lot more prepared for my gcse now - just got to do a lot of practice :)

Well explained! I use pretty much the same style, i.e. I capitalize keywords, I use the equals sign for assignment and I mark off the end of a block. I find pseudocode more useful than flowcharts. One reason for that is that it's closer to real code and easier to make than making flowcharts. You would obviously not "draw" a flowchart with the keyboard, you would need a drawing or diagramming tool and rely on using the mouse or another pointing device for that, or use a pen and paper if you're doing an exam and using a computer is off limits. It's also natural to go from a text description of a problem, and break it down to pseudocode. I find that it's often the only way to understand the problem, because the problem description is not always well written. That's usually because the author himself doesn't always know exactly what he wants a programmer to do, as he does not understand the problem well enough. I'm not referring to any particular standardized test here. I'm talking about using pseudocode as a tool for understanding a problem and translating that into real code, in a wider context, in real life. Flowcharts are great to use as a template if someone else has made them for you and they are well structured and make sense. But having to draw your own to solve a problem using code is a big waste of time, I would rather make pseudocode than flowcharts.
thanks so much! My first class was for pseudocode and it confused me a lot and just needed clarification. My class needed pseudocode and a flowchart so i got confused on what i was even doing but i got it now.

Hey, I’ve been going through my Computer science revision guide and found that my teacher hasn’t taught the class over half of what is in the revision guide, how can I learn all of it?
I'm confused for at 22:09, for the left side which I am guessing it is C++. Why is the the if statement kilometres < 0? Should it not be kilometres > 0 since it ask to continue only if kilometres is greater than 0?
Would you be able to show us how to do pseudocode in questions that use internet protocols because personally, I prefer pseudocode so much more than flowcharts but I don't know how to implement it in questions that use internet protocols like sending and receiving packets?.
Can you help to solve this question: - Scope Using pseudocode to solve a prblem, let’s identify and fix any bugs (issue with functionality, typo, something broken) to return the intended functionality of the program. See the example below to get an understanding of how one might complete this. - Problem The intended functionality of the program below is to take a list of more than 1000 numbers (not in sequence) and determine the biggest number in the list. Identify any error(s) within this pseudocode solution and provide an explanation on why you identified this as a potential problem. Let maxNumber represent the biggest number, set it to zero to start While there are still numbers left in the list Look at the next number in the list Compare it to the maxNumber If next number is smaller than maxNumber Set maxNumber to that number Report maxNumber as the biggest in the list
Thank you for providing us with this info. I just have a question about the java and C++ code, I think the if kilometers should be greater than 0. so that the amount of fuel should be multiplied.
Would you understand if the pseudocode was written like this: BEGIN NUMBER kilometers, fuel { OUTPUT {"How many kilometers will the journey be?"} INPUT {kilometers} IF (kilometers
I spent the entirety of my first year of computer science watching football videos instead of listening and going through the work my teacher was giving us. I blame him for putting me in a seat where I could take such a large advantage of the lesson
I've learned more about pseudocode from a 28 minute video that I have in over a year of college. Speaking of which, how would this work for RPG programming?
Questions I have: 1. Why does the 'amountFuel' variable have to be written at the start of the algorithm? In my opinion the FIRST TIME the 'amountFuel' variable should be written is inside the first IF statement because that's the first time the amount of fuel is going to be calculated, but I could be wrong. 2. What's the reason for the 'END IF' to be written at the end of the algorithm shouldn't it be written at the end of the first IF statement?
Two good questions: 1) In this case it doesn't need to be there, but it's good practice to initialise it with a value and putting it at the beginning in the main programming body ensures it has global scope, and so is accessible from everywhere (it would only be accessible from within that IF statement if it was initialised there i.e. has local scope). 2) END IF isn't needed if you are indenting properly, so it's not a big deal. It's just there to make it clear when the construct begins and ends. We have 2 IF constructs, hence we have 2 END IFs but at different places. It's just coincidence that the last END IF is at the end of the algorithm.
I think it is wasteful. Looping generally requires a tight control especially while loops. Just assignment is OK since it is a constant time operation. I personally would prefer the first if block to be put before everything. This prevents wasting of computer resources. I mean, there is no point assigning amount-of-fuel variable if the number-of-kilometre is zero(0); just return 0 That way, the algorithm will be fast and do only important work.
god deym i tought we can run it but demn, so actually pseudocode for solving a algorithm with computer language but it doesn't even run at computer language, so what pseudocode for? how do we going to understand if it didnt even run,how do we know if it was right or false?
The hero we need, but don't deserve. Great and informative video.

What I hate about pseudocode is there is not standard so it's very hard to practice yourself better.
Personally I think it's better for students that there is no standard, as you can make mistakes without consequence!
Psuedocode is just changing a code specific word to a more general term. Seems pointless

Let maxNumber represent the biggest number, set it to zero to start

Look at the next number in the list
Compare it to the maxNumber

When commanded in paper 2 to write an algorithm "Using high-level programming language" can I use Pseudocode??
So say if I write some python, but not proper python, would I still get marks?
Would it be wrong to have a repeat loop after the first If statement? So it repeats until the value is equal or greater than 1500z
I think it is wasteful. Looping generally requires a tight control especially while loops. Just assignment is OK since it is a constant time operation.
