== Why is this an issue?
|
|
|
|
Nested control flow statements ``++If++``, ``++Select++``, ``++For++``, ``++For Each++``, ``++While++``, ``++Do++``, and ``++Try++`` are often key ingredients in creating
|
|
what's known as "Spaghetti code". This code smell can make your program difficult to understand and maintain.
|
|
|
|
When numerous control structures are placed inside one another, the code becomes a tangled, complex web.
|
|
This significantly reduces the code's readability and maintainability, and it also complicates the testing process.
|
|
|
|
== How to fix it
|
|
|
|
=== Code examples
|
|
|
|
The following example demonstrates the behavior of the rule with the default threshold of 3 levels of nesting:
