Method 1 ： Two dimensional array

#include<iostream>
using namespace std;
int w[4][4];
int mmm(char x1[])
{
	switch(x1[0])
	{
		case 'R':
		  return 1;

		  return 2;
		case 'P':
		  return 3;
		    
	}
}
void mmm2()
{ 
	w[1][1]=w[2][2]=w[3][3]=0;
	w[1][2]=w[2][3]=w[3][1]=1;

}
int main()
{

	char S1[100],S2[100];
	int n1,n2;
	int N;
	cin>>N;
 for(int i=0;i<N;i++)
 {  
    cin>>S1>>S2;
    n1=mmm(S1);// If S1 by Rock, be S[0] by R, all n1=1 
	n2=mmm(S2);

	}
	else if(w[n1][n2]==1)
	{

	}
	else
	{

	}	
  }
	return 0;
 } 

Method 2 ：string class

#include<iostream>
using namespace std;

	cin>>N;
	string S1;
	string S2;
	for(int i=1;i<=N;i++)
	{
	    cin>>S1>>S2;
		if(S1=="Rock"&&S2=="Scissors")
		{
			cout<<"Player1"<<endl;
		}
		else if(S1=="Scissors"&&S2=="Paper")
		{
			cout<<"Player1"<<endl;
		}
		else if(S1=="Paper"&&S2=="Rock")
		{
			cout<<"Player1"<<endl;
		}
		else if(S1==S2)
		{
			cout<<"Tie"<<endl;
		 } 
		 else
		 {
		 	cout<<"Player2"<<endl;
		 }
	}
	return 0;
