How to Convert Psuedocode Into Flowchart | COMPUTER well explained

Added: 2026-05-09

[00:00:00]You have been in a situation where you meet up a question that looks like this.

[00:00:06]Where you've been taught to convert pseudo code to flow chart. Now, let me just break it down a little bit for you.

[00:00:15]So, basically, when we are talking about pseudo code, we are simply talking about this.

[00:00:22]It's under computer and it's called pseudo code.

[00:00:26]And when we are talking about flow chart, a flow chart will involve some shapes.

[00:00:32]So, now, in the question, they're asking us to convert this pseudo code, we take it to a flow chart.

[00:00:41]Now, for the flow chart, we need some shapes.

[00:00:44]And this is one of the shapes. It's an oval shape.

[00:00:48]Not a circle, oval shape, like an egg.

[00:00:52]So, this oval shape simply represents begin, start, end, stop.

[00:01:13]So, at whichever point that you see this word or this, you are supposed to put a this oval shape. So, if you can see nicely, there are these words. If you see any of these words that I've put here, the shape that you are supposed to put is the oval shape. Okay?

[00:01:36]So, the next shape that we need to know is this shape.

[00:01:44]This is a parallelogram.

[00:01:47]Also the same. This parallelogram, at whichever point you see the word enter, print, display, you are supposed to use this shape. And if you check nicely here, we've got this enter, meaning this shape will work right here. We've got uh What else?

[00:02:19]We've got print here. We're supposed to use this shape. We've got print right here. We're supposed to use this shape.

[00:02:27]The next shape that we need to know is this shape right here.

[00:02:34]It's a diamond shape. Remember, there are only four shapes that we need. So, this diamond shape, it's called a decision box.

[00:02:50]This is where the computer makes its decision. So, at whichever point you see the word if, you are supposed to use a this word. But not every if. The only if that starts here. So, you can see here there is if.

[00:03:06]I'm not going to use this shape. Only when the if is starting like it is here, this is where we need to use a decision box.

[00:03:14]Now, under this decision box, there is an instruction. Always start with is and there should be a question mark.

[00:03:22]I will explain in details what it means.

[00:03:25]The The last shape that we need to know, it's a rectangle.

[00:03:29]And this is called instruction.

[00:03:33]Instruction box.

[00:03:37]So, for the instruction box, this is where you need to put the formula. For example, here, this is a formula. At whichever point in the pseudo code, you see the formula, it's a it must be put in a the instruction box.

[00:03:53]This is what you need to know.

[00:03:55]So, now, uh let me let me just give you a situation on how you can understand these things. We all know the computers.

[00:04:05]You switch on the computer, this one.

[00:04:07]You start typing on the keyboard what you want the computer to do for you.

[00:04:11]This is a keyboard. And this computer will now start thinking.

[00:04:15]It will be in a this shape where it will be doing its thinking of what you want it to do. And then it will do a command right here on the instruction. And after that command, the whatever you were doing will come out on the screen. This is a screen. That's why I've got the word display or print. It will it will show on the screen. That's how it works. Let's now answer the question so that we can see what we're supposed to do.

[00:04:44]So, for the question that we have here, they are saying start.

[00:04:49]And according to what we said, start, we use oval shape. So, that's a start.

[00:04:59]So, the next point or the next shape that we are supposed to use here is parallelogram. According to what I told you, parallelogram represents enter. So, we're going to say enter R {comma} S. So, just copy everything the way that they look. Now, we are at this point where it's very interesting.

[00:05:29]According to what I said here, I said where we see if starting like like this, we are supposed to use a diamond shape. And this is how the diamond shape will look like.

[00:05:44]And we shall say is, okay? Is S less than R? We even put a question mark.

[00:05:53]So, this if changes to the question here. Is S less than R?

[00:06:00]We even put a question mark.

[00:06:03]And there are two options that are supposed to come out. So, here, there is an option and also here an option. So, this is yes and this is a no.

[00:06:17]Now, this side, what are we supposed to put? We are following the steps. It says print error.

[00:06:24]We know, of course, that print, according to what we said, is the same as a end of the They use the same shape as a enter. So, here, we are going to put a parallelogram and then say print error.

[00:06:45]So, we just follow what is uh written.

[00:06:48]The way it's written is what we follow.

[00:06:50]And from here, down here, cuz I'm running out of space, so I'll use this.

[00:06:56]Down here, we're going to put a some shape here.

[00:07:01]According to what we have here, there is this formula.

[00:07:06]And we said for the formula, it's supposed to be in a an instruction box.

[00:07:10]So, here, we're going to say A is equal to there R and S. Just like that.

[00:07:21]And from this point, of course, we can uh do this. There is end if. For this one, skip it. Don't write it anywhere.

[00:07:32]It's only found in a pseudo code to just show you that you are about you are moving towards ending.

[00:07:39]So, here, there is print A. You are going to use the shape for print. It's this one. So, you say print the way it looks, A.

[00:07:50]And finally, oval shape, you say stop.

[00:07:55]Because here, it says what? Stop. This is how it's supposed to be done.

[00:08:00]Hopefully, you've learned one or two things. This has been Suchanba Jacob and bye-bye.
