Basic programming skills include the ability to write code, debug code, and understand common programming concepts. These skills are essential for any programmer, regardless of their experience level.
Code is the foundation of all programming. It is the instructions that a computer follows to perform a task. Debugging is the process of finding and fixing errors in code. Common programming concepts include variables, loops, and functions.
Variables are used to store information that can be used later in a program. Loops allow a section of code to be repeated multiple times. Functions are blocks of code that can be reused throughout a program.
Learning how to write code, debug it, and understand common programming concepts is essential for anyone who wants to become a programmer.”
Data structures and algorithms
In this article, we will explore the basics of data structures and algorithms. We will learn what they are, some of the most common ones, and how they can be used to solve problems.

What Is a Data Structure?
A data structure is a way of organizing data so that it can be used efficiently. There are many different types of data structures, each with its own advantages and disadvantages. The type of data structure you use depends on the kind of data you have and what you want to do with it.
Some common examples of data structures are arrays, linked lists, stacks, queues, trees, and hash tables. We will discuss each of these in more detail later on.
What Is an Algorithm? An algorithm is a set of steps that can be followed to solve a problem or accomplish a task. Algorithms typically take some input (such as a list of numbers) and produce an output (such as the sorted list). They can be as simple as adding two numbers together or as complex as finding the shortest path through a maze.
Object-oriented programming (OOP) languages
Classes and Objects: In an OOP language, everything is an object. A class is a template for creating objects, and an object is an instance of a class. Objects have their own data (attributes) and behavior (methods).
Inheritance: Inheritance is the ability to create new classes from existing classes. This means that you can reuse code and avoid duplicating code.
Polymorphism: Polymorphism is the ability to write code that can work with objects of different types. For example, you can write a method that sorts a list of objects, without knowing the type of each object in the list.
Integrated development environments (IDEs)
An IDE is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools, and a debugger. Most modern IDEs have intelligent code completion. Some IDEs, such as NetBeans and Eclipse, contain the compiler and interpreter within themselves and are called “integrated” because they eliminate the need for a separate compilation step prior to execution of the program.
IDEs are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program in which all development is done rather than having to switch between many individual applications. This can often reduce or eliminate the need for repetitive tasks such as creating starter code files or project configurations repeatedly.
Many modern programming languages have associated IDEs that support specific language features (such as syntax highlighting) and often provide integrated build tools and debugging support as well. Some manufacturers have taken steps towards making their own tools more portable so that they may be used on different platforms (such as Microsoft’s Visual Studio). However, there are still many differences in how these tools work on various platforms; it may not be possible or practical to achieve identical functionality on all systems.
There are two main types of IDE: graphical and text-based: Textual Development Environments usually consist of little more than a text editor designed specifically for writing software code; common examples include EmacsandVim. These editors provide few if any features beyond those necessary for writing code; instead they focus on providing keyboard shortcuts or macros to reduce repetitive tasks,or plugins/addons/packages which extend their functionality. Many textual editors also support some form of plugin system which allows additional functionality to be added; this is particularly common in VimandEmacs, where there is significant overlap between the core developer community and those who write plugins.”Lightweight”IDEs also exist which offer some basic coding assistance without including many other features; one notable example is Geany.”Full featured integrated Development Environments include all the features one would expect from an advanced development environment: class browsers, project management utilities (often based around makefiles), debugging capabilities,”wizards”, etc.; examples include Microsoft Visual Studio,:jg2k17Eclipse,:pp167-8NetBeans,:p58and Intelli.
Cloud computing
Rapid elasticity: Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service models:
Cloud Software as a Service (SaaS): The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Cloud Platform as a Service (PaaS): The capability provided to the consumer is to deploy on to the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Cloud Infrastructure as a Service (IaaS): The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment models:
Private cloud: The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance.
Containers
A container is a data structure that stores one or more items of the same type. The items may be stored in an array, a linked list, or any other data structure.
A container is often used to store data that is being processed by a program. For example, a program that sorts a list of numbers may store the numbers in a container while it sorts them.
There are many different types of containers, each with its own advantages and disadvantages. Some common types of containers are:
Arrays: An array is a fixed-size container that can store multiple items of the same type. Arrays are typically used to store data that will be processed sequentially, such as a list of numbers to be sorted. The main disadvantage of arrays is that they have fixed size; once an array has been created, its size can not be changed. Additionally, accessing individual elements within an array can be slow if the array is large. However, arrays have the advantage of being very fast and efficient when it comes to processing large amounts of data sequentially. Linked Lists: A linked list is a dynamic container that can store multiple items of the same type. Linked lists are typically used to store data that will be accessed randomly, such as records in a database. The main advantage of linked lists over arrays is their dynamic nature; since linked lists can grow and shrink as needed, they do not have the fixed-size limitation imposed by arrays. Additionally, accessing individual elements within a linked list can be very fast since there is no need to search through an entire dataset for the desired element (as would be necessary with an array). However, one disadvantage of linked lists is that they require more memory than arrays because each element in a linked list must contain not only its own data value but also pointers to the next and previous elements in the list.’.

Text editors
There are many different text editors available, and the best one to use depends on your needs. If you’re just starting out coding, you might want to use a simple text editor like Notepad++ or Sublime Text. These editors have basic features like syntax highlighting and code completion. However, if you’re working on more complex projects, you’ll need an IDE with more advanced features like debugging tools and version control integration. Some popular IDEs include Microsoft Visual Studio and Eclipse.
No matter what type of text editor you choose, it’s important to learn the basics of how to use it. This includes learning how to navigate the file system, create new files and folders, and save changes to existing files. You should also learn how to use keyboard shortcuts as they can help speed up your workflow.
