Treatment. The quickest way to find dead code is to use a good IDE. Delete unused code and unneeded files. In the case of an unnecessary class, Inline Class or Collapse Hierarchy can be applied if a subclass or superclass is used.

What causes dead code?
Dead code is the part of your application that can never be executed. Common causes include: Programming errors in conditional branches. Code that will never be reached because the input data will never cause a specific branch to be executed.
What does error dead code mean?
Code that is never executed is known as dead code. Typically, the presence of dead code indicates that a logic error has occurred as a result of changes to a program or the program’s environment. Dead code is usually optimized out of a program during compilation.
Which tool can be used to identify dead code?
Using ESLint to detect and remove dead code Among many other useful things, ESLint allows us to detect unused variables in our files with its aptly named no-unused-vars rule. To enable the rule, you can simply add it to the rules object in your ESLint configuration file.

What is the difference between dead code and unreachable code?
MISRA C defines unreachable code as code that cannot be executed, and it defines dead code as code that can be executed but has no effect on the functional behavior of the program.
Why is there a dead code in java?
A dead code is just a warning message native to Eclipse or another compiler. It is not displayed in the javac core java compiler. On the other hand, the unreachable code is an error reported by the javac Java compiler. It is officially included in java as an error.
Should you remove dead code?
The larger the project, the more dead code you’ll have. It’s not a sign of failure. But not doing something about it when you find dead code is a sign of failure. When you discover code that is not being used, or find a code path that cannot be executed, remove that unnecessary code.
Why is my code unreachable?
In computer programming, unreachable code is part of the source code of a program which can never be executed because there exists no control flow path to the code from the rest of the program.
What causes unreachable code?
Unreachable code is an atom or sequence of atoms which cannot be executed because there is no way for the flow of control to reach that sequence of atoms. For example, in the following atom sequence the MUL, SUB, and ADD atoms will never be executed because of the unconditional jump preceding them.
How do I get the dead code in C++?
One approach is to use “Find All References” context menu item on class and function names. If a class/function is only referenced in itself, it is almost certainly dead code. Another approach, based on the same idea, is to remove(comment out) files/functions from project and see what error messages you will get.
Which of following is called as dead code?
Dead code includes code that can never be executed (unreachable code), and code that only affects dead variables (written to, but never read again), that is, irrelevant to the program.
What is orphaned code?
It manifests itself as variables that are declared but never used, functions that are never called, or code that is skipped because of a branch. Since the dead code is not executed, it is an error, often a logic error.
Should dead code be removed?
Removing such code has several benefits: it shrinks program size, an important consideration in some contexts, and it allows the running program to avoid executing irrelevant operations, which reduces its running time. It can also enable further optimizations by simplifying program structure.
What is an example of dead code?
A return statement can be used to make dead code. Here is an example: int div_0(double a, double b) { if (b == 0) return 1; else return 0; return a/b; // dead code here. }

What is Zombie code?
“Zombie code is an expression used to describe software functionality that is more or less abandoned or unsupported but which still appears in the current source code,” explains Daniel Stubbs, scientific analyst at Calcul Quebec and part of the Compute Canada Federation.
How can solve unreachable code in C++?
Just add a premature return while working on the code in the function or the code calling the function.
Where is the dead code in Eclipse?
UCDetector (Unnecessary Code Detector) is a eclipse PlugIn tool to find unnecessary (dead) public java code. For example public classes, methods or fields which have no references.
