How do you fix unreachable statements?
1(a) is compiled, line 12 raises an unreachable statement error because the break statement exits the for loop and the successive statement cannot be executed.

How do I get an unreachable code?
While some simple cases of unreachable code can be detected by static analysis (typically if a condition in an if statement can be determined to be always true or false), most cases of unreachable code can only be detected by performing coverage analysis in testing, with the caveat that code reported as not being …

In which type of testing unreachable code would be found?
Explanation: Code review is a software quality assurance activity in which one or several humans check a program mainly by viewing and reading parts of its source code, and they do so after implementation or as an interruption of implementation.
How do I fix error else without if?
Solution: The above compilation error can be resolved by providing correct if-elseif-else syntax as shown below. The best way to deal with error: ‘else’ without ‘if’ is always to use curly braces to show what is executed after if.
What does unreachable code mean in solidity?
Unreachable code, a part of the source code that will never be executed due to inappropriate exit points/control flow.
What is unreachable catch block error?
An unreachable catch clause may indicate a logical mistake in the exception handling code or may simply be unnecessary. Although certain unreachable catch clauses cause a compiler error, there are also unreachable catch clauses that do not cause a compiler error.

What is considered dead code?
In some areas of computer programming, dead code is a section in the source code of a program which is executed but whose result is never used in any other computation. The execution of dead code wastes computation time and memory.
