This diagnostic rule is based on the software development guidelines developed by MISRA (Motor Industry Software Reliability Association).
This diagnostic rule is relevant only to C programs. The 'default' label should be either the first or the last label of a 'switch' statement. Following this rule makes the code clearer.
Here is an example of code triggering this warning:
void example_1(int cond) { switch (cond) { case 1: DoSmth(); break; default: DoSmth2(); break; case 3: DoSmth3(); break; } }
To eliminate the warning, rewrite the code. For example:
void example_1(int cond) { switch (cond) { case 1: DoSmth(); break; case 3: DoSmth3(); break; default: DoSmth2(); break; } }
This diagnostic is classified as:
