Programming is a topic that I'm sure all of you know. It's something we use in our everyday lives, and it can be used for both good and bad purposes. At its core, programming refers to writing a set of commands or instructions for the computer to follow so that it can process data and store information. It is simply the communication between human input and machine output that involves written codes.Programming may involve simple instructions such as simply adding two figures. It may also involve complex processes such as organizing data to come up with analytical reports.

What Is Programming Language?
A programming language is a text that comprises a formal set of notations and rules that generate instructions and algorithms to produce an output. It allows us to communicate easily with a computer.Several programming languages have distinct features that promote seamless communication between us and the computers. The most common programming languages are:
1. Java
Java is the most popular programming languages in the world of programming. Large businesses and higher learning institutions are some of the entities that heavily use Java.
2. Python
Python is the most preferred programming languages. This is because of its user-friendliness and easy-to-understand syntax.
3. JavaScript
JavaScript is a primary programming language that is most commonly used in web development processes and creating websites.
4. Ruby
Ruby is a user-friendly programming language. It is preferred by many beginners hoping to integrate themselves into the world of programming quickly.
5. C
C is considered one of the ‘parent’ programming languages that have been around for ages. It is considerably complex to learn, and only seasoned programmers are known to use it regularly.
What Are the Uses of Programming?
A. Used in automatic billing of products in supermarkets and convenience stores.
With automatic billing, it serves customers fast and with high accuracy.
In addition, programming can help these businesses to create important reports, e.g., monthly sales reports.
B. Use in Calculators.
When we input a set of commands in calculators, e.g., ‘2+2’, and the calculator immediately solves this instruction by giving us the result, i.e., 4, as the output.
C. Used in Search Engines like Google and Bing
A regular search query entails you typing a search term on the search bar of Google. Google finds all related information through the web and then displays the most relevant search engine results, which is the output.
D. Used in Chat Applications
When using Chat, it can send and receive messages when typed. Once you hit the “send” button on your mobile phone, laptop, tablet, or desktop, the computer understands the instruction and delivers your message(s) to the intended recipient(s).
What Are the Different Types of Programming?
1. Procedural Programming
This is programming that involves executing a sequence of statements to obtain a result. It uses features such as heavy loops and a variety of variables. A good example is a process of printing out information.
2. Functional Programming
It is a programming language that involves using stored data and recursive functions to get results from your operations.
3. Logic Programming
This form of programming allows programmers to produce declarative statements that enable a machine, e.g., a computer, to give you analysis regarding these statements.
How To Get Started with Programming as A Beginner?
1. Learn The Basic Concepts
You should first grasp the basic terms, e.g., syntax, data structures, tools, etc., and the concepts and understand them well.
2. Choose The Most Appropriate Language.
It is advisable to go for beginner-friendly programming languages like Python and JavaScript. This will help you to ease into programming slowly. It will also help you to understand essential procedures like loops and procedures and be easy to read and understand.
3. Regularly Practice.
Constantly test yourself and the skills you have gained to see if you are on the right track. Honing these skills by practically experimenting with them from time to time will help you get there faster than merely reading theoretical concepts.
Which Programming Languages Are for Beginners?
Beginners venturing into programming must select the most appropriate programming languages that will help to develop your coding skills. Some of the best programming languages for beginners include:
1. JavaScript
It is arguably the most commonly used programming language today, even in social media platforms, like Facebook and YouTube. This programming language is effective for both front-end and back-end web development processes and is very useful in developing mobile apps.
2. Python
Python is very useful in developing websites and mobile apps because it has many tools and sophisticated infrastructure. These features make Python effective in the fields of machine learning, back-end development, and artificial intelligence.
3. Java
Java is very popular when it comes to developing android apps, banking software, etc. It has a lot of beneficial features that include high security, scalability, and robust memory.
Common Mistakes When Programming
As a beginner, making programming mistakes is a common occurrence and carefully spotting these errors during the testing period will save time and money. These common mistakes include:
A. Failure To Follow a Consistent Writing Style
For programming to be effective, a programmer needs to follow a consistent writing style. A consistent writing style will allow you to direct more time to solve the problem. An inconsistent writing style will be seen in the lack of consistency in the games throughout the process and by programs that do not use consistent indentation.
For example, a capitalized name may denote a class. An indented word may mean that it is within an ‘if statement.’
B. Using Functions That Are Too Long
Using many lines of coding in your functions will make it difficult for you to understand what your role does and means effectively. Such large functions make it very difficult for programmers to debug and maintain them as they are confusing.
Often, you may find programmers using extensive functions that have more than fifty lines or containing more than eight if statements. If your function becomes too big during programming, you can create subfunctions.
C. Failure To Validate the User Input
Failure to perform basic checks related to the user input will make your program vulnerable to hacking. The program you create should therefore not create a situation where the users input overflows the internal buffers. In addition, if your program uses the user input to build queries, it is imperative to ensure that this user input has zero controls that may otherwise leak into the question. If it does leak into the query, your program becomes susceptible to hacks.
C. Mishandling The Exception Mechanism
This feature is very effective when it comes to addressing errors. However, one standard error that many programmers encounter here is catching an exception that they had no intention of in the first place.
Here’s a quick example:
// delete the file
Try
{
deleteFile(filename);
}
// ignore the error if the file is not present
catch(…)
{
}
If the file that the programmer expects to be deleted is not present, they expect that the delete file() will give out a ‘FileNotFoundException.’ However, the exception that they hope is caught does not go as planned, and as a result, everything is ‘caught.’
This may happen because of two reasons. Either the file is missing, or the exception you have integrated into the function is unrelated.
D. Failure To Validate the User Input
Failure to perform basic checks related to the user input will make your program vulnerable to hacking. The program you create should therefore not create a situation where the users input overflows the internal buffers. In addition, if your program uses the user input to build queries, it is imperative to ensure that this user input has zero controls that may otherwise leak into the question. If it does leak into the query, your program becomes susceptible to hacks.
E. The Programmer Does Not Maintain a Program Log.
A program log is crucial for recording all the activities during programming and the people behind the actions. For example, a programmer may encounter a situation where they are given an “it didn’t work” response during programming.
A program log would be instrumental in providing the programmer with vital information like the individual’s identity associated with this particular failed request. They would then use this identity to establish essential details about the failed action, including when the failed request was communicated and why it failed.
However, fixing errors becomes a difficult task if the programmer does not have a program log where all events are recorded.
