Understand the working needs of digital coding methods

Anyone who knows something about digital coding memory methods knows that coding is the focus of digital memory, and it is required to compile a set of codes based on one's own preferences The system is good, but how to compile a set of codes suitable for my memory? The teacher will share with you several preparation methods.

Common number memory methods: homophonic memory method, image transformation method and meaning transformation method. Moreover, these three memory methods are also coding ideas that are very easy to learn and understand.

When you start learning to code, one question you may ask yourself is "What language should I learn first?"

The most exciting thing about learning to code - and sometimes even One of the overwhelming things is how much there is to learn.

But instead of just focusing on learning a specific technology, it helps to learn the basics - the building blocks that you can peel back the layers of abstraction to understand. Basic principles common to all technologies.

Understanding what coding is at a basic level will make problem solving easier and give you a better understanding of how different technologies work.

< p>This article explains the basics of computer coding and what programs it consists of, while also giving some advice on how to take the first steps in learning how to code.

What is coding for beginners?

Computer coding, also known as computer programming, is a way of telling a computer what to do

Coding is a way of telling a computer how it should behave - what it needs to do. The exact actions and how to take those actions in an effective and efficient manner

Specifically, coding is the process of creating and then providing a detailed set of instructions to the computer that will be executed carefully in sequence. /p>

The set of instructions is called a program or code

Computers are very smart machines, but they rely on humans to do their jobs.

In short, coding is. The art of human-computer communication. It helps us solve problems and create useful new tools for the community, such as applications or websites, and enables us to analyze and process large amounts of data.

Overview of the coding process

Coding is about problem solving.

When writing code, you use logical reasoning to break down problems into smaller and smaller action steps to ultimately arrive at conclusions and solutions.

The computer understands everything literally and pays extreme attention to detail

Make a small mistake in the code - such as a misspelling in a word, a missed semicolon, and tell the computer to repeat an action. But not telling it how and when to stop repeating it - will result in error messages

These errors are called bugs in your code

Identify the possible error and find the cause of the problem. , and then fixing the errors so that the code works as expected is called debugging

This is a critical part of writing code and learning how to write code

Why algorithms are important in coding.

Figuring out the exact instructions to give the computer so that it can complete a specific task is the hardest part of coding and problem solving.

Computers don't make any assumptions, they do exactly that. The way they are told to do it. This means there should be no ambiguity in the instructions they receive.

The instructions need to be clearly defined and have the correct number and sequence of steps that the computer should take to solve the problem.

The set of step-by-step ordered instructions used to solve a problem and for the computer to complete each task is called an algorithm.

Algorithms are sequences of actions that need to be correct, efficient, precise and to the point, and they should leave no room for misunderstanding.

Algorithms are not just reserved for computers to follow. Humans also use algorithms every day.

An example of an algorithm we often use is following cooking recipes.

The recipe is the algorithm. You need to follow a series of steps in the recipe in the correct order to get the desired end result.

How to write pseudocode to plan an algorithm

The way to organize, plan ahead and write down the steps or algorithm you need to follow is to write pseudocode first.

Pseudocode is an informal way of representing an algorithm.

Pseudocode has no specific syntax. It is written in plain and readable English (or any other natural human language) using some technical jargon.

It is written just to allow programmers to use simple phrases to understand the reasoning and logic behind the code/steps that need to be written to solve the problem.

After doing this, the programmer writes the code that is actually executed by the computer.

Pseudocode is a simpler version of computer code and is the first step before writing any computer code.

For example, suppose you want to write a program that asks the user for a password and checks whether it equals "1234".

If the password equals "1234" then you let them into the system, otherwise they are denied.
