Introduction to Programming Language and History of C Language

Introduction to Programming Language

Programming Language is a computer language that is used by programmers and  developers to communicate with the computer. It is a set of instructions written in any specific language ( C, C++, Java) to perform any specific task. A programming language is mainly used to develop desktop applications, websites & Mobile applications.

Types of Programming Language:

Low-Level Programming Language- (LLL)

It is Machine dependent (O and 1).The processor runs low-level programs directly without the need of a compiler or interpreter. So, the programs written in Low level language can be run very fast.

High Level Language-(HLL)
High level language is designed for developing user friendly software programs & websites.
This programming language requires a compiler or interpreter to translate the program into machine language to execute the program.
The main advantage of HLL is that it is easy to read, write & maintain. It includes python, Java, Javascript, php, C#, C++ etc.
Object Oriented Programming Language is based upon the object in this programming language programs are divided into small parts called objects. It is used to implement real world entities Like inheritance, polymorphism, abstraction encapsulation. It makes the program reusable, efficient & easy to use.
The main advantage of OOP is that it is faster and easier to execute, maintain, modify as well as debug.
E.g:- C#, Java, Python etc

Procedural programming language is derived from structured programming & based upon the procedure called concept. It divides a program into small procedures called Routines or functions. C, FORTON, PASCAL, BASIC, etc.

Translator: A program written in high level language is called as Source Code to convert this source code into machine code translators are needed. A translator makes a program take written source code as input & convert it into a program in target language as output. It also detects & reports errors during translation. 

There are two different type of translator & these are :-

1) Compiler: Compiler is a translator which is used to convert programs in High level to Low level language. It translates the entire program & also reports the error in the source program encountered during the translation.

Source< — Compiler—>Target  

2) Interpreter: It  is also a translator which is used to convert programs in high level language to low level language. Interpreter translates line by line & reports the error once it encounters during the translation. It directly executes the operation specified in the source program when input is given by the user.

3) Assembler: It is a translator which is used to translate the assembly language code to machine language.

Introduction and History of C Language

C programming language was created by Dennis Ritchie, an American computer scientist, while working at Bell Labs in the early 1970s. Alongside Ken Thompson, Ritchie also contributed significantly to the development of Unix operating system, which played a crucial role in popularising C.

 

Brief History:
Origins: The roots of C can be traced back to the Multics project, an ambitious effort to develop a time-sharing operating system at Bell Labs. Dissatisfied with the complexities of Multics, Ken Thompson and Dennis Ritchie began developing their own simplified operating system called Unix in 1969. As Unix evolved, the need for a flexible and efficient programming language became apparent, leading to the birth of C.

Development: Dennis Ritchie began working on C around 1971, drawing inspiration from earlier programming languages like BCPL and B. He aimed to create a language that provided low-level access to hardware while still offering high-level abstraction. By 1973, C had started to take shape, and it was soon used to rewrite portions of the Unix kernel and other system software, cementing its place in the computing world.

Standardization: As C gained popularity outside of Bell Labs, efforts were made to standardize the language to ensure compatibility across different systems. In 1983, the American National Standards Institute (ANSI) established a committee to develop a standard for C, leading to the creation of ANSI C or C89 in 1989. This standardization laid the groundwork for the widespread adoption of C in both academia and industry.

Evolution: Over the years, C continued to evolve, with subsequent revisions and enhancements. The International Organization for Standardization (ISO) released an updated version known as C99 in 1999, followed by C11 in 2011. These revisions introduced new features and improvements while maintaining backward compatibility with previous versions.

Legacy: C's influence extends far beyond its original intended purpose. It became the language of choice for system programming, embedded systems, and software development in various domains. Its simplicity, efficiency, and portability made it a favorite among programmers, laying the foundation for countless other languages and frameworks.

Modern Relevance: Despite the emergence of newer languages and technologies, C remains relevant today, particularly in areas where performance and control are paramount. It continues to be widely used in operating systems, device drivers, embedded systems, and high-performance computing. Additionally, many modern programming languages, including C++, Objective-C, and Rust, are directly descended from C or heavily influenced by its syntax and semantics.

In summary, the C programming language, created by Dennis Ritchie at Bell Labs in the early 1970s, revolutionized the world of computing with its simplicity, power, and portability. From its humble beginnings as a system programming language for Unix, C grew to become one of the most influential and widely used programming languages in history, shaping the evolution of software development and leaving an indelible mark on the digital landscape.

                           

Career Options After BCA

Hello everyone! Today I will be sharing information about career options after BCA. If you have seen my previous post, you must have seen that I have shared information about the specialisation in the BCA course. So if you are doing any specialisation then it is  very good for you to make a career in that particular field. But If you are not doing any specialisation in a BCA course then also there are many options in which you can make your career. If you are reading this post right now then you might be wondering why I am sharing all this information. You could have searched all this information on Google by yourself and got a detailed answer to your queries, but I want to make the information short,  insightful and interesting to read for you.

Well, without further qualifications, it is possible to build a career after a BCA course. There are a number of courses that BCA graduates can undertake for their further education including MCA, MBA, MCM and many other courses which are best for higher education. Beside these master courses, there is a wide range of short term courses for BCA graduates. Here are some of the top career options you can explore after completing your BCA:

• Technical Analyst
• Data Scientist
• Web Developer
• Digital Marketer
• Software Developer Trainee
• Banking Sector
• E-commerce Executive
• Educator
• Cyber Security Expert
• Blockchain Developer

Well here comes the most important question: how to decide in which particular field you want to go. For that you need to understand yourself and find which field interests you, what are you good at.

There is one thing that I want all of you to remember: always focus on the subject that boosts your interests and always keeps you active to learn it.

If you like my posts, do share it to all your BCA friends and tell them to read and give feedback through comments and ask their queries related to BCA.

Why I choose BCA ?

Why BCA ?

Why BCA? Well, this is the question that is often asked by people when I tell them that I am pursuing

BCA. Then they ask about my stream in senior secondary education, and the most astonishing part is when I tell them that I have a PCB stream. 

This is because they think that the student who chooses biology should go for NEET or any other medical profession. But this is not the truth: a student who has studied biology cannot make a good career in the technological field. That's why BCA is an option for them to go into the world of technology. 

Then many people have a question for you: if you want to make your career in the IT field, why haven't you opted for math subjects in your senior secondary education? Many people have the mindset that only B.Tech. is the best option if they want to go into the IT field or the tech field. They think that BCA is a useless course, and you can't make a good career in IT if you are doing BCA. 

Well, it's not true. That's why here I am writing this blog for all the people who are doing BCA and want to do BCA to know about its reality and give some motivation to them because many people are going to ask them these types of questions. 

Students who are interested in the technical field but, due to some reasons, choose a different stream or belong to any other stream, and later they get to know that they want to make their career in the IT field, then BCA is a great choice for them👍.

The languages that you'll learn in this course are C, C++, Java,  HTML, Python, SQL.

But one thing that I want to say is that "skills matter the most; if you have skills, then you can achieve your goal.". 

BCA is a 3-year professional undergraduate course for people who want to go into the field of technology and belong to any stream, whether from science, commerce, or the humanities and arts. It consists of six semesters, and you can also specialize in particular domains, such as 👇 :

1. IT
2. Data Analytics
3. Cyber Security
4. Cloud Computing
5. Digital Marketing

You can get more details about its fee structure and the subjects that you are going to study in this course from Google. 

As, I am writing this blog to give you some knowledge and answers to the people who are going to ask you these questions. So I am trying to make it short and fun to read.

So now I think that you can give answers to people, feel a little motivated, and remember the thing that matters most👍💁.

If you want to know more about BCA and need help regarding any subject, you can ask me in the comments, as well as if you want a blog on any other topic related to BCA.

Please do share this blog and suggest me a topic on which you would like to have another post.
