A switch-label can be placed anywhere within the statements that form the body of a switch statement, potentially leading to unstructured code. To prevent this from happening, the scope of a case-label or default-label shall be the statement forming the body of a switch statement. All case-clauses and the default-clause shall be at the same scope.
== Noncompliant Code Example
----
switch (x) {
case 1: // Compliant
if (foo) {
case 2: // Noncompliant
break;
default: // Noncompliant
break;
}
break;
default: // Compliant
break;
}
----
== See
* MISRA C 2004, 15.1 - A switch label shall only be used when the most closely-enclosing compound statement is the body of a switch statement.
