= Motivation  =

Code conventions are important to programmers for a number of reasons 

- 80% of the lifetime cost of a piece of software goes to maintenance. 
- Hardly any software is maintained for its whole life by the original author. 
- Code conventions improve the software readability, allowing programmers to understand new code more quickly and thoroughly.
