C++ problem, could you please with this probelm “Game” through only using bitwise operators & the following:
1-Control and repetition structures for input validation.
2-Bitwise operators to handle the underlying bits in a variable.
3-Apply formatting rules to console output.
4-Replicate the gameplay of the game.
