A programming language is a set of specification and rules. It is better to stick to those while you are coding.
Anyone having basic arithmetic ability and knowledge of for loop can code a Fibonacci series. Since one can understand the problem and apply his/her logic to solve. But writing a good code and writing a code is two different things.
Writing a code is just like typing the problem logic and make it work. Whereas the writing a good code is to present it beautifully so it looks like a piece of art.
A "good code" has to be well structured, clean and understandable.
Good code
Using appropriate names for variables , functions, classes etc.
Comment as much as you can , for which is not obvious .
Divide whole problem into modules.
Proper indentation.
Logical organization of statements.
Appropriate error handling mechanism.
Prefer clarity to "efficiency" read as premature efficiency.
Declare where you use or declare all data at same place.
Choosing appropriate data structure for the problem.
Code as per the the programming language's style conventions or standards.
Code that i hate to work with.
Basically it will be a right opposite of "good code". To name a few
naming variables to anything rather than some meaningful name.
Consistently bad indentation.
No comments to important parts of code.
Code striving for premature efficiency.
Repeating same code which is better to be modularized.
Doing more that one thing in a module.
But in real work environment one has to work with other fellows who habitually wrote opposite of "good code". They tends to follow writing style rather than coding style.
And when you are sharing your code to such a guy and he is making changes to it .. which will diminish the beauty of your code, then you have to write this post and ask them to go through it.
