Please help me code the following! Please read carefully.

Full points will be awarded, thanks in advance

Queue and LongInt Problenm Consider the LongInt class we have implemented in programming assignment 7. Code a new public function named shiftleft( ) that shifts its long integer left by just one bit (but not by a digit). Assume that all public and private functions listed in the following header file (of course, except shiftleft )) have been already implemented. However, you must not use operatort and operator- to implement the shiftleft ) function. (Otherwise, this question is too easy.) Hint: "shift left by 1 bit means multiply by 2".
