To start learning about the basics of programming languages, first take the example of the international language – English. In English, every sentence follows a basic structure i.e., subject, object, and verb combine according to grammar rules to complete a sentence. Similarly, coding languages follow a set of rules defined by syntax. The basics of a programming language include:
In nonprofessional terms, programming language is the language of computers. Developers use coding languages to communicate with computers, write codes, and make computers work as per their requirements. Two basic categories of programming languages include:
Programming is fundamental to modern technologies like Artificial Intelligence (AI) and Machine Learning (ML) and their implementation. Python is widely used to perform data analysis using AI and ML. As the trend of automation is on the rise, programming languages become essential in manufacturing industries as well. Moreover, coding languages play a crucial role in technological advancements linked to the defense and military sectors.Also read: Top 10 Successful SaaS Companies Of All Times
A compiler is software that developers use to write codes in different languages. The compiler translates high-level code to machine-level code, low-level binary code, or binary numbers that the computer understands.
Variables are placeholders to store data values. Every program processes some data to produce the desired output. This data is stored in variables that are defined in the program and held in the computer’s memory.
Functions are reusable pieces of code that take in some data and process it to give the desired output. Functions help make the code short and easy to interpret.
Conditionals are used in code when a decision has to be made based on some conditions. They execute different pieces of code based on the condition.
Loops make programming easy in the sense that they eliminate redundancy in the code. Instead of rewriting the code snippet for repetition, loops perform the repetition with a single line of code.
Memory management is a key concept in programming languages. All the data in the code and the code itself is stored in memory. Therefore, it is essential to manage memory access memory space and avoid memory wastage.
Syntax refers to the proper combination of symbols, keywords, variables, operators, and punctuation in the code. The compiler checks the syntax and notifies any errors. Any mistake in the syntax will force the compiler to throw an error without compiling the code. Let’s illustrate this using a simple example code written in C. In C, every command ends with a semicolon. No semicolon indicates a syntax error as illustrated in Figure 1 and Figure 2.
Semantic refers to the interpretation of code. Semantic ensures whether the code performs its intended functionality or not. Let’s see a Python code meant to add two numbers (8 and 2) in Figure 3. There is no syntax error in this code. However, there is a semantic error. The code actually tries to add two numbers, but the second number (2) is declared as a string and not an integer (line # 5), which makes the code semantically incorrect and thus the error.
To learn programming, it is a good idea to first focus on the basics mentioned at the start of this article, and practicing these basics helps in understanding semantics and syntax.Also read: Top 10 IoT Mobile App Development Trends to Expect in 2021
In 1843, Ada Lovelace wrote the first algorithm intended to run on Charles Babbage’s analytical engine, and since then, multiple languages have come into existence. A brief history is given next:
So, a journey through the basics of programming languages opens up a fascinating world where languages serve as fundamental tools for shaping the digital landscape. From the elementary concepts of syntax, variables, and data types to the more complex areas of functions, conditions, and memory management, each element plays a key role in creating efficient and effective code. Understanding the nuances of coding languages is like mastering a new form of communication that combines human creativity with machine precision. For those who want to delve into the world of programming or improve their programming skills, the first step is to master the basics outlined in this article.
