[previous] 0570 [next] This switch case label of 'essential type' '%1s', is not consistent with a controlling expression of essential type '%2s'.
Switch statements

This message is issued whenever a switch controlling expression and a case constant expression have different essential type categories.

Consider using a cast or review use of a 'U' suffix (if applicable) to match the essential type of both expressions.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 0570 --*/

void f0570 (int a)
{
  switch (a)
  {
  case '0':             /* Message 0570 */
  case '0' + 1:         /* Message 0570 */
  case 2U:              /* Message 0570 */
    break;
  default:
    break;
  }
}
