[previous] 0572 [next] This switch case label of 'essential type' '%1s' is not consistent with a controlling expression which has an essential type of lower rank (%2s).
Switch statements

This message is issued whenever a switch controlling expression and a case constant expression have the same essential type category, but the controlling expression is of lower rank.

Consider removing an 'L' suffix or using a cast to match the rank of both expressions.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 0572 --*/

/********************************
 * OPTIONS: -ex LONGLONG
 *******************************/

void f0572 (long a)
{
  switch (a)
  {
  case 0LL:             /* Message 0572 */
  case (long long) 1:   /* Message 0572 */
  case 2:               /* OK */
  case 3L:              /* OK */
    break;
  default:
    break;
  }
}
