MISRA switch staement - Hanumanthappa E - 18-10-2017
Hi everyone,
Can anyone give an example of MISRA-C "switch" statement pls....
Re: MISRA switch staement - dg1980 - 18-10-2017
I assume you mean fully compliant, right?
Code:
switch (i)/* essentially integer (for bool use if/else), needs at least two clauses*/
{
case 0:/* empty fallthrough compliant*/
case 1:
doSomething();/* statement or comment required*/
break;/* unconditional break in every case clause required
default:/* default case required as last (or first) clause*/
/* statement or comment required*/
break;/* unconditional break in default required*/

An example of a compliant switch statement is:
Code:
typedef signed char int8_t;
extern void use_int8(int8_t i);
void R_16_1 ( int8_t input )
{
switch ( input )
{
case 0:
{
use_int8 ( input );
break;
}
case 1:
/* { .. } not required at this level */
use_int8 ( -input );
break;
default:
{
use_int8 ( 0 );
break;
}
}
}
