== Why is this an issue?
|
|
|
|
A ``++switch++`` statement is a control flow statement that allows you to execute different blocks of code based on the value of an expression. It provides a more concise way to handle multiple conditions compared to using multiple ``++if-else++`` statements.
|
|
|
|
If you only have a single condition to check, using an ``++if++`` statement is simpler and more concise. ``++switch++`` statements are designed for handling multiple cases, so using them for a single condition can be overkill and less readable.
|
|
|
|
This rule raises an issue when a ``++switch++`` statement has only one ``++case++`` clause and possibly a ``++default++`` one.

switch (condition) { // Noncompliant: The switch has only one case and a default

case 0:

doSomething();

break;

doSomethingElse();

Use a ``++switch++`` statement when you have multiple cases to handle and an ``++if++`` statement when you have only one condition to check.
