welcome to today's lesson we are still continuing with our topic which is computer and calculator but this time around today we want to see how we can now convert a flowchart to a suitable since last time we are converting from a super code to a flowchart now we want to to the other way around which is converting a flowchart to a pseudo code so you already know what a flowchart is and we already defined what a pseudo code is but just for the sake of those that are joining us for the first time maybe let me just go through one of these important ships here so computer lesson is just based on these important shape data on the board so this shape here the auto-ship it simply means that on store so when you are starting a program this is where you enter witness copy you also end up in the similar shape then when we are inputting something when you are inputting something we always use this program shipped even when you are putting something we also use the parallelogram shape here then we also have an action box to simplify things for the sake of your exams we just say in the action box there whenever you see a formula this is where we put a formula and in the decision box that's why I came to get to put the questions so when you see if in the pseudocode when it lands creating a project this is where you say is okay so input their formula here and also the success of writing any flow chart is dependent on an individual knowing the formula so the first thing that you have to deal with is not a formula of the particular thing that you are dealing with for example if you want to write a for a flow chart to show how volume is calculated the first thing is not a formula for volume once you know the formula for volume then you can easily construct a flow chart okay having given that background let's just now continue we go to the question that we have so this question simply says convert the following flow chart to a pseudo code now a pseudo code has got a specific language that youth and a specific way of writing so please let me demonstrate and explain a few things on how it is supposed to be done okay so here with the stacks as you can see stacked there so she stacks just trade the stacks then the enter era here on the pseudocode we finished we don't a straight symbol here we finish on the future that's why we rarity the symbol so instead of saying entire era as we are going to say enter radians so it also has it stacked in stats like you indent a bit so it will start enter radius okay when you asked here the is on the flow chart here it changes to the if when you're writing a sugar also here it's a question if radius is less than zero then okay so now here if radius is less than zero so here a same display error message so if then display error message error message display error message then they are saying I don't know if we have enough space would have continued each layer and written era must be positive must be positive then we go to the next one now so he every time before you write a formula now it's in an action so before you write the formula always remember to put the weight else so here is simply same errors area so we are saying else area is equal to this formula have been given near else our area here is equal to half x squared radius squared radius x sine theta so you continue that site we should design me filter make sure you have enough space continuing these sentences okay then before you can display what you are calculating there is always this funny thing that is put and if okay and if me that's when you say display display area because that is what you are doing then having done that is a stop so this stop should be in the same line there stop and you are done you have converted from a flowchart to a pseudo code now you can do a quick practice of this one you simply erase this thing and try to construct it by using this to prove if you have done is the correct thing okay so this is how simple it is computer business paper to take questions like once you understand the paper to take questions you can also easily do with it the paper one tech question because they will just need you to know the formula and understand these four basic shapes and you're a woman right you are a show above the total seven max that comes in your final exam that is - max paper one and five max Peppa - thank you for listening to this lesson today - next time
