How to Start programming.






First things first, you can't rely on books to learn CS. You need to have access to the internet and online resources. Books are good for the theoretical parts(Data Structures and Algorithms, Discrete Math, theoretical CS, Cryptography, etc. I will tell you about these later on). So, you just need an internet connection to study.

So, as I mentioned in an earlier post, C++ is a good start. It's a good language with various applications, its still in use, and its accepted in almost all programming contests. Python is another good language for beginners, but its easy and has got its demerits as a first language(you will find it tough to move to C++ if you know Python as your first language, whereas learning Python after C++ is trivial). I'll tell you a step by step approach to learn programming.
1.  course on C++.

There are many other courses on Coursera, Udemy, MITOCW, etc. but they are of some other languages. If you find a good one on C++ then its good. You can try it.. But I did this one(this is a pretty informal course, but I feel that formal courses should be done after you are done with the having the basics of one language on your tips. There are many places where you can practice questions. First be clear with all the basic functionalities and learn them by heart.

I personally find books useful. Books have questions in them, and theory too. Reading a book will really tell you much more than what you can learn from an online tutorial. I guess you can start with this very famous book called Let us C++.
2. Online practice source.

There are many other sites like CodeChef, HackerRank, CodeForces, HackerEarth, etc. I personally find HackerRank good, but hackerearth is the best, because it requires thinking about the problem from scratch without any precoded stuff.

Happy holi in coding style

WISH HAPPY HOLI USING C LANGUAGE: follow these steps : 1. open code blocks and select new project: 2. select console application : 3. click on next button and choose c language: 4. provide project title as well as project path: now you can see that the main window is open , so write the code here: #include <stdio.h> #include <wchar.h> #include <stdlib.h> #include <locale.h> int i,j; void delay() {     for(i=0; i<1000; i++)         for(j=0; j<3000; j++)         {} } void delay1() {     for(i=0; i<100000; i++)         for(j=0; j<3000; j++)         {} } void change() {system("COLOR 9");         delay1();         system("COLOR C");         delay1();         system("COLOR 5");         delay1();     ...

Interesting Facts about C++.

C++ is an object-oriented language. No. C++ is a multi-paradigm programming language. C++ supports OOP, procedural programming, generic programming, template meta programming and functional programming. It is one of the biggest strengths of C++ that it is a multi-paradigm programming language. Programmers should be free to pick their own programming style, and that style should be fully supported by C++. Why should I define a  class  just to print “Hello world”? This quote by  Bjarne Stroustrup  really makes sense.      “Certainly not every good program is object-oriented, and not every object-oriented program is good.”  image source: Wikipedia  C++ is just an extension to C and is a super set of C. C & C++ both are different programming languages having different rules and standardized by different committees. C & C++ both have diverged since C99. There are many features of C99 and C11 which aren’t offici...
