Programming

YES! If you can code and apply logic, take it. Passion, perseverance and patience to solve problems will make you a great CS undergrad. I was in the same boat. I took up Engineering Design in 12th, (something unique I know). It was easy, scored a 95+ in boards but deeply regretted taking it up and missing out on Computer Science since I have been into Computers since 7th grade. Advice:
- Most important advice would be to listen in your PSUC class (1st year) and sincerely code in the lab. This will walk you through the absolute basics of programming. - Join a technical club, IE-CSE, LUG, IEEE's CS division etc. - Keep following coding, technology, ACM, IEEE blogs everyday to learn about developments in research and the market. - Never stop learning. Make google your friend. If you see 'Virtual Functions' written on the projector's slides, google it, read about it, discuss with your friend circle (important) and implement it correctly in the lab. - Try reading books like 'How to solve it by Computers', 'Art of Computer Programming', 'Structure and Interpretation of Programs'
- Try coding as much as you can. Practice makes you perfect. /advice&get;
I didn't know what '#include' did before I came to college and now I can call myself at par with other programmers here. It's just interest and how much time you are willing to put into it. Don't take it as coursework, read stuff up everyday. One last thing
Computer Science is a Science and not just a programmer's haven. You should also focus on how programs are run (Compilers), stored (Databases, Big Data), managed (OS), taught (AI, Machine Learning), communicate (Networks), executed (Computer Architecture), analyzed (debugging), displayed (Graphics) and the math behind each algorithm. This is equally important and if not worked upon, then you're just a script kiddie.

If you already have programming experience in other languages and really want to understand how C works, skip to the next paragraph. Rather than a book, I'd recommend starting with this online tutorial: C Tutorial - Learn C - Cprogramming. Com. It's pretty good at teaching the basics. Then make your own small project using what you've learned - something that shows your knowledge of the concepts, but won't take you weeks to make. Maybe a card game, like solitaire or war, which prints to the console. Then, when you really want to understand what C is doing to your code, continue to the next paragraph. C is an interesting language, because you can't truly understand it without understanding exactly how a computer works. To this end, I recommend "Computer Systems: A Programmer's Perspective". This book teaches C from the bottom up, starting with the processor and working its way up through assembly code to the C code that represents it. It teaches you to see C code as a thin layer over assembly, and helps you to understand why things like caching and out-of-order memory access can affect your programme. Unfortunately, this book is used as a textbook in many courses, and as a result is highly overpriced. Google searches may be able to turn up alternative copies. I have the second edition, which is very good and probably all you need. The newer third edition covers the x64 instruction set in more detail. If you want to focus on x64 programs, it may be worth the extra cost to get that version.

Dear Priyank,
Your question is not a surprise since WordPress is more popular than ROR and PHP. WordPress is a content management system developed with PHP. WordPress has a market share of 90.5% (as of Jan 2017). WordPress is used by 58.6% of all the websites whose content management system we know. This is 27.4% of all websites. (according to W3Tech). PHP is a programming language (PHP: Hypertext Preprocessor), which is used to build WordPress CMS. To Answer your question:
If you like to have a Content Management System for your website - WordPress is a good choice. If you want to write your own Content Management System or anything sort of a complex custom web application, you would really require PHP. If you like to extend WordPress with your own custom plugins - you will still require PHP, HTML and CSS.
