    keeping score trough a loop

    hello
    im writing a rock paper scissors game and i want to keep the users scoreand computers score after the user says they want to play again. how would i do this?
    Code:
    #include<iostream>
    #include <cstdlib>  //to use rand function
    #include <ctime>  // to use time as the seed for rand
    using namespace std;
    
    
    /*Randall Foor
    Rock Paper Scissors program
    10/7/10
    */
    
    int main(){
    	int number,usernumber;
    	char repeat,userpick;
    
    	
    
    	do{
    		int userscore,compscore;
    		system("cls");
    		srand(time(0));
    		number = 1 + (rand() % 3) ;
    		
    		userscore=0;
    		compscore=0;
    		cout<<"\nYour Score: "<<userscore<<endl;
    		cout<<"Computers Score: "<<compscore<<endl;
    		cout<<"Pick either (R)ock,(P)aper, or (S)cissors. \n";
    		cin>>userpick;
    
    		if(userpick=='r'|| userpick=='R'){
    			usernumber=1;
    			cout<<"so you picked rock";}
    		if(userpick=='p'|| userpick=='P'){
    			usernumber=2;
    			cout<<"so you picked paper";}
    		if(userpick=='s'|| userpick=='S'){
    			usernumber=3;
    			cout<<"so you picked scissors";}
    	
    
    		if(usernumber==number){
    			cout<<"\nuser picked "<<userpick<<" and the computer picked the same thing, so it is a draw";
    			userscore++;
    			compscore++;}
    		if(usernumber==1 && number==2){
    			cout<<"\npaper covers rock, you lose";
    			compscore++;}
    		if(usernumber==1 && number==3){
    			cout<<"\nrock beats scissors, you win";
    			userscore++;}
    		if(usernumber==2 && number==1){
    			cout<<"\npaper covers rock, you win";
    			userscore++;}
    		if(usernumber==2 && number==3){
    			cout<<"\nscissors cuts paper, you lose";
    			compscore++;}
    		if(usernumber==3 && number==1){
    			cout<<"\nrock beats scissors, you lose";
    			compscore++;}
    		if(usernumber==3 && number==2){
    			cout<<"\nscissors cut paper, you win";
    			userscore++;}
    
    		cout<<"\nYour Score: "<<userscore<<endl;
    		cout<<"Computers Score: "<<compscore<<endl;
    
    	
    
    
    
    
    		cout<<"\ndo you want to repeat<y or n>?\n";
    		cin>>repeat;
    	}while(repeat=='y'|| repeat=='Y');
    
    system("pause");
    	return 0;
    }

    declare and initialize the variables to hold the scores outside of the loop
    ╔╗╔══╦╗
    ║║║╔╗║║
    ║╚╣╚╝║╚╗
    ╚═╩══╩═╝
