[previous] 4109 [next] Right hand operand of logical operator is an arithmetic or bitwise expression.
Arithmetic type - Operands

The left hand operand of this logical AND (&&) or logical OR (||) operator is derived from a bitwise or arithmetic operator. This is probably a mistake; perhaps a bitwise AND (&) or bitwise OR (|) was intended ?

For example: 


/*PRQA S 2017,3198,3199,3203,3227,3408 ++*/

extern void foo(unsigned int a, unsigned int b, unsigned int c)
{
    int r;

    r = a && (b * c);                     /* Message 4109 */
    r = a || (b * c);                     /* Message 4109 */
}
