Top Programming Languages That Will In Great Demand In 2021
A decade before people who were expert in programming languages was considered as intelligent (in IT field). And now-a-days also, people who have the knowledge of programming languages are in great demand. So, let's look to the history of programming languages.
A programming language is the means by which instructions and data are transmitted to computer. In other words, Programming languages acts as an interface between a computer and a human being. All computer languages have vocabulary of their own.
The computer language can be classified under two categories :
• Machine Language
• High Level Languages
Machine Languages
Machine Language is the language that is understood by the computer. This language is expressed zeros and one (called binary language). However, Binary Language is so complicated that it is very difficult to use and to be understood by human beings.
High-Level Languages
Programmers, being humans, can work better and faster with meaningful words and figures. It is more easy for them to write programs in languages using regular English words. Such languages are called high-level languages. Some examples of high-level languages are BASIC, LOGO, C++, PASCAL, COBOL, FORTRAN, C, HTML, etc.
To make the computer understand the program written in a high-level language, a special software is required to translate it into machine language. Such softwares are called language processors or translators. The translators are of two types:
• Compilers
• Interpreters
Compilers :
A compiler translates all the statements of a program in one go and creates a new file in the machine language. A program written by the programmer in high-level language is called the source program and when it is converted into the machine language program, it is called the object program.
Interpreters :
An interpreter translates a program line by line. It translates one line of the program, executes the translated instruction, and then moves on to the next line. It displays the errors of one line and only after correction of the errors, the control goes to the next line.
GENERATION OF PROGRAMMING LANGUAGES
First Generation Programming Languages
First-generation language (machine language) is the lowest level computer language. Information conveyed to the computer by the programmer as binary instructions. Binary instruction are similar to the on/off signals used by the computers to carry out operations The languages consist of zeros and ones. In 1940s and 1950s, computers were programmed by scientists sitting before big control panels with switches, so that they could input instructions as zeros and ones.
The biggest disadvantage of this language is that it is machine dependent, i.e., each type of processor requires its own machine language.
Second Generation Programming Language
Assembly or assembler language was the second generation of computer language. By the late 1950s, this language had become very popular. It consists of letters of the alphabet. This makes programming much easier than using the machine language. Here, the abbreviation are used for programming instructions. These abbreviations are actually mnemonics which are easy to remember, like C for compare, MP for multiply and so on. Like machine language, assembly language is also machine dependent.
Third Generation Programming Language (High-level Language)
Both the above generations of languages had their own disadvantages, So, in order to overcome these problems, high-level languages were developed. The introduction of the compiler in 1952 started the development of third generation computer languages. These languages enable a programmer to create programs using commands that are similar to spoken English. Third-level computer languages have become the major means of communication between the digital computer and its user, High-level languages are not machine dependent.
Fourth Generation Programming Languages
Fourth generation languages (4GL) attempt to make communication with computers much easier and simpler. They are also called very high level languages. For a program, if we have to write about hundred lines in a program of high-level language, the same program can be written in 5 to 10 lines in a 4GL.
Examples of fourth generation language are SQL (Structured Query Language), JAVA, PROLOG (an artificial intelligence language), HTML, Python, etc.
So, which are the top Programming Languages?
There are a number of programming languages present to learn but not all are not beneficial. IT companies are hiring programmers who have the knowledge of different programming languages. Here are some of the top Programming languages that are in great demand and pays out very well.
1. Python
Python is one of the most popular programming language at this time as it it is easy to learn. One can do web designing, application setup as well as 2D and 3D modelling using python. Popular websites like YouTube, Quora and Pinterest uses this programming language. Not only this, python programming language is used in the field of A.I. also. You could choose Data Science also and it is well known that salary of a data scientist is much more. Average salary of a Python developer is $76,000.
2. JAVA
Most of the computer applications and websites are build using Java. It is an object oriented structural language. It can be run on any type of operating system whether it is Windows, Android or iOS. It is also used in the field like big data popular applications and websites like ok YouTube Google Amazon and Twitter prefer Java programming language average salary of a java programmer is $79,000.
3. C Programming Language
It is also very popular programming language. Major section of the games like pubg and free fire are build using the C languages like C# and C++. Popular websites like Bing and Visual Studio are based on C language average salary of a C programmer lies between $7000 to 8000.
What will be the cost of learning these programming languages online?
See, there are many online platforms which will help you to learn these programming languages and the best thingis that some of them are absolutely free of cost (you may need to pay for certification but free option will also be there). You can try online platforms like Udemy to get certified. Well, Harward University has also open many online courses for free. You can search for CS50 to try these courses from Harward University. If you are willing to get certified by Harward edX then you have to pay $99.
So, after all these information you can choose the one you want. I will recommend Python as it is easy to learn and is in great demand this time. Start learning your favourite programming language.
All The Best!
