Nested ``++switch++`` structures are difficult to understand because you can easily confuse the cases of an inner ``++switch++`` as belonging to an outer statement or expression. Therefore nested ``++switch++`` statements and expressions should be avoided.

Specifically, you should structure your code to avoid the need for nested ``++switch++`` statements or expressions, but if you cannot, then consider moving the inner ``++switch++`` to another method.

void foo(int n, int m) {
|
|
switch (n) {
|
|
case 0:
|
|
switch (m) { // Noncompliant; nested switch
|
|
// ...
|
|
}
|
|
case 1:
|
|
// ...
|
|
default:
|

// ...
