What is Programming Language ??

A programming language is a set of instructions that helps a computer perform tasks. The most common computer languages are text-based formal languages, but they can also be expressed graphically. Its description of a programming language is basically divided into two components. One component is called syntax (form), and the other is called semantics (meaning). Programming language theory is the subfield of computer science that studies the designs and implementations of programming languages. As an example, human beings can talk and understand each other in their language. Computers can’t understand the languages of human beings, so they developed programming languages that are understandable by computers.




However, the programming language is a subset of computer languages. Another usage of programming languages as theoretical constructs for programming abstract machines A computer scientist named John C. Reynolds emphasizes that the specification of a programming language is intended for execution. He also argued that the behavior of computers depends on the programming language, which considers textual and graphic formats. a Programming languages differ from natural languages. Programming languages allow humans to communicate instructions to machines. There are some languages called markup languages. These are not programming languages like XML, HTML, and so on. It is a structured query language.





The first computers, like Colossus, were programmed without any programming language. Slightly later, the programs were written in machine language. Here, programmers need to write each instruction in a numeric form called binary language. which is the only language understandable by computers or hardware that can execute it directly. After a while, the development was called “second generation programming languages.” These programs help to make programming more accessible and readable for humans.



Growth of programming language


In the 1980s, C++ was a combined object-oriented system programming language. One important trend in language design for programming large-scale systems occurred during the 1980s. It increases focus on the use of either modules or organizational units of code. Ada and ML developed a notable module system in the 1980s. similarly In the mid-1990s, the world of technology saw the rapid growth of the Internet. which creates great opportunities for new programming languages. Fourth-generation programming languages aim to provide a high level of abstraction to the computer hardware. Fifth-generation programming languages are based on solving problems using constraints given to the program.






The surface form of programming language is known as syntax. Typically, most programming languages are entirely textual. This language includes words, numbers, and punctuation, the same as natural languages. On the other side, some programming languages are graphical in nature, using relationships between symbols to specify programs.


Examples of programing languages


There are too many different types of programming languages available; here are some of the main ones :



C language


The C language is a general-purpose computer programming language. This language was created in the 1970s by Dennis Ritchie. C is equally important and commonly used on computer architectures that range from the supercomputer to the embedded system. That is the imperative procedural language, which supports structured programing as well as variable scope with a static type system. It is designed to compile with very low access to memory.



Java language


Java is a class-based, high-level object-oriented programming language. It is a general-purpose programming language that the programmer intends to write only once. The advantage of Java is that it runs on any platform that supports Java without having to be recompiled. Java is one of the most popular programming languages in use, according to the data on GitHub. As a result, the Java programming language was used to create this website, on which you are currently reading a blog.



Python language


Python is a high-level language. It is also called a general-purpose programming language. Python supports multiple programming paradigms. structure, object-oriented, and functional programming. Python 0.9.0, the first version, was released in 1991. Up until then, Python consistently ranked as the most popular programming language.



PHP language


PHP is a general-purpose scripting language. This language is very helpful in web development. PHP is typically processed on a web server by a PHP interpreter. It generates code for any type of data, such as HTML or binary image data. PHP is not only used in web development; it is also used in other programming tasks like web context and graphical applications.
