Description:

Using relational or logical conjunctive operators in a switch expression is very likely to be wrong and is at best confusing.

Example:

switch( a > b ) /* WRONG */
{
    case ´b´:
    case ´c´:
      j = 4;
      break;
}

Example:

switch( a ) /* RIGHT */
{
    case ´b´:
    case ´c´:
      j = 4;
      break;
}
