[previous] 3426 [next] Right hand side of comma expression has no side effect and its value is not used.
Redundancy

The right hand operand of this comma operator is redundant. It generates no side effects and its value is not used. What is the intention ?

For example: 


/*PRQA S 2017,3199,3203,3227,3408,3417,3440 ++*/

extern void foo(int p, int j)
{
    int n;

    n = (++p, j + 1);           /* OK           */

    ++p, j + 1;                 /* Message 3426 */

}
