C++ left shift negative number

WebThe behavior is undefined if rhs is negative or is greater or equal the number of bits in the promoted lhs. For unsigned lhs, the value of LHS << RHS is the value of LHS * 2 RHS, reduced modulo maximum value of the return type plus 1 (that is, bitwise left shift is performed and the bits that get shifted out of the destination type are discarded).
