Why should we learn 'C' language first ?


Before I begin why a future computer programmer should learn 'C' language, let me give you an analogy: Suppose if you want to eat Pizza, you have three options to get it. You can either directly go to a Pizza store and buy a freshly baked yummy pizza, or you can get stored pizza dough from the store and heat it at your home in an oven (cheaper way than the earlier method) or through the harder way like getting the ingredients like dough, sugar, milk, water, mix it and prepare the pizza from the scratch. This is the cheapest way to make a pizza, but as a cook you will understand the process and procedure how a Pizza is made. 


High-level Languages like Java, Python fall into first category where a programmer can directly use the defined functions, libraries to achive his programming objectives. Hard-core programmers who want to learn programming in detail will follow the last approach mentioned in the above paragraph. 'C' can be called as a middle-level language which stands between low-level languages and high-level languages. 


First, let’s make a distinction between someone who wants to just learn any programming language (the guy who just wants the pizza) from someone who has the desire to be a polyglot programmer (the artisan baker). Don't get me wrong, there are many great reasons to learn a programming language, and even if you just learn one higher level scripting language like Python or JavaScript, you’re still a programmer. Mastering any single language is still a challenge and a worthy goal.


However, the programmer I’m addressing here is someone who wants to understand programming at a deeper level just for programming’s sake. This is someone who naturally has a desire to become that polyglot programmer. Surely, there are advantages to learning C first; you won’t get seduced by a language like Python and never come back. In fact, if I were teaching high school students, I would almost certainly teach them a higher level language like Python first. Then I would take my best students and teach them C second. If I were teaching a class of computer science engineers, I would probably just start with C.


Advantages:

1. Personally, I do think there are advantages to learning C first over C++ or Java. When you work in languages like Java, C# and even Python, you immediately start moving away from learning the fundamentals of a programming language and you start learning associated libraries and frameworks. But with C you get a few library calls, you stay focused on the semantics of the language longer, and C often forces you to think harder and deeper about what’s happening under the hood.


2. C is the language of compilers, interpreters, editors, operating systems and embedded programming. When you learn to program in 'C' you almost have to gain an understanding of how programs execute. You know what things like register, stack, heap and memory mapped IO mean. 


3. Simplicity & Speed: C is simple, elegant and wicked fast; it’s compact and efficient. Because C has RAW POINTERS, BITWISE OPERATORS, and the keywords: extern, volatile, static, and register—meaning you’ll understand more about writing efficient code than you can obtain from any higher level language with difficulty. The only thing that will teach you these things any better is a low level language, and with modern processors I wouldn’t wish assembler on anyone.


4. Fewer distractions: 'C' is not an object oriented language so you don’t get distracted by things like inheritance and polymorphism. I’m not saying these aren’t important concepts, it’s just that you can simplify things a bit by learning straight procedural programming first. In fact, once you've learned C, and written a couple of embedded programs on some single board computers, learning C++ is a natural next step. You will need to get someone to pry your fingers off the macros and preprocessor directives but other than that it will be straightforward. I would be tempted to teach C with a C++ compiler, and just highlight the few differences that weren’t backwards compatible with a strict C compiler.


5. Embedded programming: My final argument for learning 'C' language is tied to doing embedded programming. As a programmer I always get a sense of satisfaction when I deliver any working piece of code. Making a computer do what you want can be satisfying. But when I integrate my embedded code with some custom hardware that makes things happen outside of the computer—from moving a robotic arm to generating a precisely timed waveform—I get an incomparable thrill. That thrill only happens because of C. 


6. C is the most commonly used programming language for writing operating systems. The first operating system written in C is Unix. Later operating systems like GNU/Linux were all written in C. Not only is C the language of operating systems, it is the precursor and inspiration for almost all of the most popular high-level languages available today. In fact, Perl, PHP, Python and Ruby are all written in C.


By way of analogy, let's say that you were going to be learning Telugu, Kannada, Tamil & Malayalam. Don't you think knowing Sanskrit would be helpful? Just as Sanskrit was the basis of all of those languages, knowing C will enable you to understand and appreciate an entire family of programming languages built upon the traditions of C. Knowledge of C enables freedom.


'C' Training Course Objective:

Based on the above facts, the main objective of this course is to inculcate programming culture in a student to achieve programming objectives in future. The student will be able to write a 'C' program based on the logic developed as a part of the program. This course h helps them understand next level programming languages, tools and applications easily. IT Industries across the globe evaluates a student's knowledge in programming based on his/her understanding in 'C' language concepts. We Provide lot of logical and day-to-day life examples to help them understand the subject easily. 

About 'C' Language

Although numerous computer languages are used for writing computer applications, the computer programming language, C, is the most popular language worldwide.

  • Everything from micro controllers to operating systems is written in C since it’s very flexible and versatile, allowing maximum control with minimal commands. 

If you are interested in a career in computer programming, it would be wise to start by learning the C programming language. 


  • There are numerous benefits from learning C; however, the most important benefit is that the C programming language is recognized worldwide and used in a multitude of applications, including advanced scientific systems and operating systems.
  • Another benefit of learning the computer language, C, is that it’s the basic language of all advanced computer languages. For example, if you want to learn C++, which is an object oriented language, you need to know the C language well beforehand. 
  • Once you master C programming, you can easily learn another specified language.

Programming in C is fairly easy because it uses basic commands in English. However C is a compiled language so after you type your commands, in order to execute your program, you need to run it through a compiler to transform the human-readable form into machine-readable language. 


There are many C compilers available today. If you are a student working on a university UNIX computer, you can use the compiler for free. Otherwise, you can purchase Microsoft’s Visual C++ environment, which compiles both C and C++ programs. In addition, there are some free compilers you can use over the Web. 


In today’s world, a computer programmer needs to be able to communicate with colleagues in different countries. Therefore it’s important that even if they don’t speak the same verbal language, at least the computer language is understandable to all.
