What is Pseudocode? An Introduction.
Summary
TLDRThis video script introduces the concept of pseudo code as a planning tool for programmers. It clarifies that pseudo code is not a new programming language but a way to define program logic before coding begins, similar to flowcharts. The script emphasizes the importance of planning for easier application development and the role of pseudo code in verifying the correctness of algorithms. It also discusses the utility of pseudo code for non-coders to understand and validate the steps needed to solve a problem. The video mentions that any text editor can be used to write pseudo code, including Visual Studio Code, for its readability and ease of use.

Q & A
What is pseudo code?
-Pseudo code is a way to define what we want to do in a program before we actually write the program. It's not a new type of language but a method to plan and outline the steps needed to solve a problem in a natural language, making it easy to read and understand for both coders and non-coders.
Why is it important to create pseudo code before writing a program?
-Creating pseudo code is important because it helps in planning the application more effectively. It allows you to check if the logic and algorithm are correct before you start coding, making the development process smoother and more efficient.
How does pseudo code relate to flowcharts?
-Pseudo code and flowcharts serve the same purpose: to create a design or plan before coding. Both are used to outline the steps to solve a problem, but while flowcharts are more visual, pseudo code uses natural language to describe the steps.
What is an algorithm?
-An algorithm is a series of steps that need to be performed to solve a problem. In the context of coding or computer science, it refers to the logical sequence of operations to be executed by a computer to achieve a specific task.
Why might someone prefer using pseudo code over flowcharts?
-Some might prefer pseudo code over flowcharts if they are working on a smaller program or if they are more inclined towards a textual representation of the steps. Pseudo code can also be easier for non-visual learners or those who find natural language more accessible.
In which language should pseudo code be written?
-Pseudo code should be written in a natural language that is easy for the intended audience to read and understand. English is commonly used, but if the audience speaks another language, that language should be used instead.
Can pseudo code be written without any special software?
-Yes, pseudo code does not require any special software to be written. It can be written on paper or using basic text editors like Notepad or Google Docs. The choice of tool depends on what is most convenient for the user.
What is the purpose of showing pseudo code to non-coders?
-The purpose of showing pseudo code to non-coders is to allow them to verify the steps of the algorithm or the solution to a problem. Even if they do not understand how to code, they can read through the steps and confirm if the logic is correct.
What tool is mentioned in the script for writing pseudo code?
-The script mentions using Visual Studio Code as a tool for writing pseudo code, due to its readability with a black background and white text, and its large font size which is good for video demonstrations.
How does the script suggest using pseudo code in the development of an application?
-The script suggests using pseudo code as a planning step in the development of an application. It should be used to outline the steps to solve a problem in a natural language before starting the actual coding process.

📝 Introduction to Pseudo Code
This paragraph introduces the concept of pseudo code as a planning tool in programming. It clarifies that pseudo code is not a new programming language but a method to define program actions before coding begins. The speaker emphasizes the importance of planning to simplify the application development process. Pseudo code is likened to a flowchart in serving as a design blueprint, helping to verify the logic of an algorithm, which is a series of steps to solve a problem. The paragraph also touches on the utility of pseudo code for non-coders to understand and approve the steps of a solution.

hello there everybody this is a short
series on how to create pseudo code now
you might be asking what is pseudo code
is this a new type of language the
answer is no pseudo code is a way for us
to Define what we want to do in a
program before we actually write the
program now you might ask well why would
we do that well the better you plan the
easier it is to create your application
and so we want to do this Pro process of
create a design figure out what we need
to do before we actually start trying to
do it now if this sounds a lot like a
flowchart you're actually correct
flowcharts and pseudo code both serve
the same purpose that is to create that
design before we start coding to let us
check to see hey is our logic correct in
our algorithm now what's an algorithm if
you remember correctly it's just a
series of steps we need to perform
in order to solve a problem it doesn't
even have to be a computer problem
technically but in our case what we're
going to look at is going to be solving
coding or computer types of problems now
you might think well why are there two
different ways of doing this flowcharts
and pseudo code well flowcharts are very
good if you have a smaller program or if
you're highly visually inclined you like
to be able to visually see
step by step by step pseudo code is
going to much more of what we call a
natural language in our case English if
you were doing in any other country that
has a different language then you would
use that language there's nothing
special about it in English it's just a
matter of is it easy for you and other
people to read understand and verify the
goal being that you take this to a
person and you say hey is this what
needs to happen they may not understand
how to code it but they can read through
the steps and go yes and they can sign
off on it and so that's what pseudo code
is it's just a plan for how we're going
to write our code in a natural language
that way we can show it to non-coders
and have them verify their algorithm or
the steps to solve our problem is
correct now one things I want to let you
know is you do not need any type of
software actually to write stud code
when I started doing this years and
years ago we wrote it out on paper and
that's all you technically need of
course in today's technological World
it'd be silly to do that so you might
write it in something like Microsoft
Word or you might write in something
simple like notepad or another text
editor I'm going to be using a tool
called Visual Studio code which I
actually use for writing my code but I'm
going to write my pseudo code in it as
well for a couple reasons number one
it's very easy to read it has a black
background with white text that's a
little bit easier especially with a
larger font size so it shows up better
on these videos and is easier to look at
if I'm staring at screen for a large
amount of time do you have to use that
no absolutely not use whatever you find
to be easiest and you might be working
at a computer lab where they don't have
that and but they have notepad then use
notepad or maybe you can log into the
internet and go into your Google Docs
that's fine too the goal is to write a
natural language to solve the problem
find a tool let you do that and then
we'll get started check out the next
video and how we're going to start our
very first simple application and write
in studo
code
