Code examples

The following code example fails the check and will give a warning:

void example(long l, short s) {
  l * ( s + s ); /* Implicit conversion of (s + s) */
}

The following code example passes the check and will not give a warning about this issue:

void example(long l, short s) {
  l * s + s; /* No composite conversion */
}
