What Will I Learn?
  • It is a course dedicated to concept in which function calls itself.
  • This course will lay down the foundation of Recursion(function which calls itself).
  • Students will get a good hands-on with Linux Operating system as programming examples are explained on linux gcc compiler.
  • C is reasonably close to the machine. Students will learn various optimization techniques in order to become the expert programmer.

What is the course about?
This course provides a thorough  introduction to the C programming language which is the core of the UNIX/Linux operating system and other embedded systems.
The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
Recursive functions are very useful to solve many mathematical problems, such as calculating the factorial of a number, generating Fibonacci series, etc.
Technically, a recursive function is a function that makes a call to itself. To prevent infinite recursion, you need an if-else statement (of some sort) where one branch makes a recursive call, and the other branch does not. The branch without a recursive call is usually the base case (base cases do not make recursive calls to the function).
Programming assignments and laboratory exercises are required to do by students. Please remember that this is a serious course on programming. I believe that programming language like C cannot be learned in few hours. It required continuous practice. Students may have to put a lot of efforts in order to become expert in programming and make the best use of this course.
What kind of material is included?
1. This course consists of high quality training content using quality videos with industry oriented hands-on examples.
2. I have tried to include the juice of my 10 years of Programming experience in this course.
3. The focus is on giving real life essential tricks and skills.
4. This course will have sets of online programming assignments and objective type quizzes.
5. I suggest students to take this course with pen and paper handy. Note the important points and take part in discussions. The exercise is the most important part in learning any language. I advise students to take the problems after each section.
How is the course structured?
1. A perfect blend of theory and programming.
Why take this course?
1. Learning C programming language is basic to learn all other programming languages such as C++, Java, Python, etc. Because, all other advanced programming languages were derived from C language concepts only.
2. This course will tends to replace text books on C programming ie it will be a complete reference of Recursive Functions.
3. You will learn how programming languages work with data, what program flow is, and how to use functions, methods and routines, Recursive Functions.
4. You will also get step-by-step instructions on how to create simple and advance C programs and how to run them.
5. For the college going students, this course helps in improving grades in college curriculum and increases the chances at the final Campus Interview.

Who is the target audience?
  • IT professionals with little or no C programming experience
  • Software professionals
  • School Students who are beginning in programming language.
  • Computer and IT hobbyists

User-defined Functions
3 Lectures 28:38

All functions have a type: they return a value  of that type whenever they are used.
In this tutorial, you will learn about different approaches you can take to solve a single problem using functions.

Preview 09:44

Example program for with arguments & with return value: In this program, integer, array and string are passed as arguments to the function. The return type of this function is “int” and value of the variable “a” is returned from the function. The values for array and string are modified inside the function itself.

Preview 10:41

A compound statement (also called a "block") typically appears as the body of another statement, such as the if statement. Declarations and Types describes the form and meaning of the declarations that can appear at the head of a compound statement.

Recursive Functions DFS
1 Lecture 13:50

Every recursive call must simplify the computation in some way.
There must be special cases to handle the simplest computations.

I  was apparently not a diligent student. I worked with C/C++ and HTML, CSS, JavaScript since 12 years. I speak to the world on software freedom. From the beginning of my career I have always worked in large and small teams. While programming has been more of a individual activity, it is the collaboration in teams that can make and break a project. I have been interested in algorithms and data structures and its implementations especially in Java since university.

I am a co-author of various manuals, and has edited and reviewed more than a dozen other books. I wrote columns that provided keen insights into the little algorithmic nuggets that we use in our programs. My favorite books includes  "Writing Efficient Programs", "More Programming Pearls" and "Programming Pearls". The best programmers not only continuously improved the quality of their work, they also influence other members of their team.

I learned about project management and team interaction working at various organisations. I still believe that humans are still at the beginning of the code revolution. Programmers and users are still imitating what came before, and haven’t even imagined all that could be in the future. One thing I am sure of is that code is a type of language, based on the same logic as Sanskrit, and for the first time in history, language can change the physical world. Programming is a literature.

I've always had a passion for teaching in seminars and corporations during my consulting projects. My online school eLearningMedium gives me the opportunity to share my knowledge with students of all backgrounds and experiences across the globe! I'm really excited for this opportunity to bring to you real-world practical experience!

I've plans of making some of the courses about Algorithms and Data Structures, Java, HTML5, Software Engineering and Software Project Management. I give all my heart into creation of courses. I always try to explain everything the easiest possible way. I'm sure that my courses will help you in the adventure.
