V622. First 'case' operator may be missing. Consider inspecting the 'switch' statement.

Jul 09 2012

The analyzer has detected a potential error: the first operator in the 'switch' operator's block is not the 'case' operator. It causes the code fragment never to get control.

Consider this example:

char B = '0';
int I;
...
switch(I)
{
  B = '1';
  break;
case 2:
  B = '2';
  break;
default:
  B = '3';
  break;
}

Assignment "B = '1';" will never be performed. This is the correct code:

switch(I)
{
case 1:
  B = '1';
  break;
case 2:
  B = '2';
  break;
default:
  B = '3';
  break;
}
