Do developers care about code smells?
An exploratory survey. Despite the fact that the detection and removal of code odors has been well researched over the past decade, there is still an ongoing debate as to whether or not code odors should be considered significant conceptualizations of code quality issues from a developer perspective. …

Why does the code smell bad?
Code smells are generally not bugs; they are not technically incorrect and do not prevent the program from working. Instead, they indicate weaknesses in the design that can slow down development or increase the risk of bugs or failures in the future. Therefore, a smell of code is a driver for refactoring.
How do you make the code unmaintainable?
Unmaintainable code comes from five main practices:
- Naming: Use single letters, typos, and a baby name book.
- Coding style: obfuscate, ‘optimize’, avoid consistency.
- Code structure: copy and paste, breaking encapsulation, using global/static members, unnecessary wrapping.
- Documentation: lying, stating the obvious, leaving placeholders.

Is there a way to get rid of code smells?
Identifying and removing code odors, as seen above, is a tedious and undefined process with no particular outcome whether the software would be odor-free or not. Also, since it is nearly impossible to find and remove all odors manually, the use of automated code review tools that can identify odors becomes a necessity.
What does the smell of program mean?
Code smell, also known as bad smell, in computer programming code, refers to any symptom in a program’s source code that possibly indicates a deeper problem. And with that as the basis of the term, I give several examples of what code smells look like and how we can identify them.
