Hi here is a C++ code, I have finished that, but can someone help me to simplify my code or maybe write in another way? For the .h part I think I don't need any changes there. But for the PowerballLottery.cpp part I think that can be simplified. Also, for the game.cpp, can you help me to provide some more test cases there? Really appreciate!

so here are my code.

PowerballTicket.h

#ifndef POWERBALLTICKET_H #define POWERBALLTICKET_H

class PowerballTicket { public: PowerballTicket(int ball1, int ball2, int ball3, int ball4, int ball5, int powerball); int getBall1(); int getBall2(); int getBall3(); int getBall4(); int getBall5(); int getPowerball(); private: int mBall1; int mBall2; int mBall3; int mBall4; int mBall5; int mPowerball; };

#endif

PowerballTicket.cpp

#include "PowerballTicket.h"

PowerballTicket::PowerballTicket(int ball1, int ball2, int ball3,int ball4, int ball5, int powerball) { mBall1 = ball1; mBall2 = ball2; mBall3 = ball3; mBall4 = ball4; mBall5 = ball5; mPowerball = powerball; }

int PowerballTicket::getBall1() //get method { return mBall1; }

int PowerballTicket::getBall2() { return mBall2; }

int PowerballTicket::getBall3() { return mBall3; }

int PowerballTicket::getBall4() { return mBall4; }

int PowerballTicket::getBall5() { return mBall5; }

int PowerballTicket::getPowerball() { return mPowerball; }

RandomNumber.h

#ifndef RANDOMNUMBER_H #define RANDOMNUMBER_H

class RandomNumber { public: RandomNumber(int min, int max, bool minInclusive = true, bool maxInclusive = true);

// supply a number between min and max inclusive int random(); private: int mMinimum, mMaximum; };

#endif

RandomNumber.cpp

#include "RandomNumber.h"

#include #include

using namespace std;

RandomNumber::RandomNumber(int min, int max, bool minInclusive, bool maxInclusive) : mMinimum(min), mMaximum(max) { if (mMinimum > mMaximum) { swap(mMinimum, mMaximum); } if (!minInclusive) { mMinimum++; } if (!maxInclusive) { mMaximum--; } }

int RandomNumber::random() { static random_device rd; static mt19937 generator(rd()); uniform_int_distribution<> distro(mMinimum, mMaximum);

return(distro(generator)); }
