Solution:

Player.h file:

#include<string>

using namespace std;

class Player{

private:

int play;//variable

public:

string getPlay();//variables

void setPlay(string Play);

void setPlay(int play);

};

string Player::getPlay(){

if(this->play == 1){

return "rock";

}

else if(this->play == 2){

return "paper";

}

else if(this->play == 3){

return "scissors";

}

return "invalid";

}

void Player :: setPlay(string Play){//set players string play

if(Play == "rock"){

this->play = 1;

}

else if(Play == "paper"){

this->play = 2;

}

else if(Play == "scissors"){

this->play = 3;

}

}

void Player :: setPlay(int play){//set players int play

this->play = play;

}

Drivercode.cpp

#include <iostream>

#include "player.h"

using namespace std;

void displayWinner(string com, string player){//define winner

if(com== "rock" && player == "rock")

cout<<"It's a tie"<<endl;

else if(com=="rock" && player =="paper")

cout<<"Player wins"<<endl;

else if(com=="rock" && player=="scissors")

cout<<"Computer wins"<<endl;

else if(com=="paper" && player=="paper")

cout<<"It's a tie"<<endl;

else if(com=="paper" && player=="scissors")

cout<<"Player wins"<<endl;

else if(com=="paper" && player=="rock")

cout<<"Computer wins"<<endl;

else if(com=="scissors" && player=="scissors")

cout<<"It's a tie"<<endl;

else if(com=="scissors" && player=="rock")

cout<<"Player wins"<<endl;

else if(com=="scissors" && player=="paper")

cout<<"Computer wins"<<endl;

}

int main() {

int computerPlay;//varriables

int lastPlay;

string userPlay;

Player computer;

Player player;

cout<<"Type rock, paper, scissors: ";//get users play

cin>>userPlay;

player.setPlay(userPlay);//set users play

do{

computerPlay = rand() % 3 + 1;//get computers random play

}while(computerPlay == lastPlay);//set computers play

lastPlay = computerPlay;

computer.setPlay(computerPlay);

cout<<"Computer played: "<<computer.getPlay()<<endl;

displayWinner(computer.getPlay(), player.getPlay());

cout<<endl;

return 0;

}
