How can I increase My programing efficiency and Knowledge.....?

Question

Give me Good Techniques and Books ..

Answer 1

Read book about programming, code, read again :)

Answer 2

To be 'GOOD' in programming is something that you can achieve by either 'being God Gifted' or 'Countless analysis of the programs of God Gifted'. So unless you are sure that you are the next Einstein , reading books on algorithms are a definite way to improve your coding or I should say Problem Solving skills.
Try Solving puzzles on websites like codechef , hackerrank etc.

To have 'Knowledge' in programming can be achieved over a month of holidays by doing one of the following (or both)
👉Build a website.
👉Build a game.

The challenges you face during doing this projects are enough to make you a standard knowledgeable coder.
I recommend you to start with basic website, my favorites include "library management" , "School management" , 'FBI Classified information'(based on levels of clearance) which clear concepts of RDBMS like normalization. Try using different types of database s in different projects (eg MongoDB) to familiarize yourself with other trends.
For a game it's totally up to you, I started with tic tac toe+(N x N board)

Try to best yourself with every iteration i.e. including more features that the previous one or improve in look and feel.

Hope this helps
