WebApr 16, 2014 · In C/C++ there is no a &&= b;. Logical AND a && b is bit like a test for 1 bit. If the first "bit" is already 0, than the result will always be 0 no matter the second. So it is not necessary to evaluate b if the result is already clear from a. The C/C++ standard allows this optimization. Bitwise AND a & b performs this test for all bits of a and b.
