#include <iostream>
#include <time.h>
#include <string>
using namespace std;
void kids_game(int gen, int choice){
    if(gen == choice) cout<<"Draw\n";
    else if(gen == 0 && choice == 1) cout<<"You win\n";
    else if(gen == 0 && choice == 2) cout<<"Computer wins\n";
    else if(gen == 1 && choice == 2) cout<<"You win\n";
    else if(gen == 2 && choice == 1) cout<<"Computer wins\n";
    else if(gen == 1 && choice == 0) cout<<"Computer wins\n";
    else if(gen == 2 && choice == 0) cout<<"You win\n";
}
int main(){
    int choice, gen;
    string picks[3] = {"Scissors", "Rock", "Paper"};
    char c;
    srand(time(NULL));
    do{
        cout<<"Make your decision\n 0. Scissors\n 1. Rock\n 2. Paper\n";
        do{
            cin>>choice;
            if(choice < 0 || choice > 2) cout<<"\nInvalid choice, try again\n";
        }while(choice < 0 || choice > 2);


        gen = rand() % 3;
        cout<<"\nYour pick: "<<picks[choice]<<endl;
        cout<<"Computer pick: "<<picks[gen]<<endl;
        kids_game(gen, choice);
        cout<<"\nPlay again? (y, n)\n";
        cin>>c;
    }while(c == 'y' || c == 'Y');
    return 0;
