Hi! I am trying to modify the game rock, paper scissors but I'm having a hard time to loop a certain case in a switch statement

Question

Here is the code. I wanted to make a loop of the cases (if possible) whenever the user wanted to continue the game. I'd appreciate it if you could give me some advice. Thank you in advance!

#include<iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main()
{
int m, number,usernumber;
char repeat,userpick;
int userscore,compscore,value;
value=0;
userscore=0;
compscore=0;

cout<< "Choose a mode\n"
"(1) Normal\n"
"(2) Fun\n"
"Enter the number of the mode you want: ";
cin>>m;
system("cls");

repeat:
while(true)
{
switch (m)
{
case 1:

srand(time(0));
number = 1 + (rand() % 3) ;

userscore=userscore+value;
compscore=compscore+value;

cout<<"\nYour Score: "<<userscore<<endl;
cout<<"Computers Score: "<<compscore<<endl;
cout<<"Pick either (R)ock, P(A)per, or (S)cissors. \n";
cin>>userpick;

if(userpick=='r'|| userpick=='R'){
usernumber=1;
cout<<"\nso you picked rock";}
else if(userpick=='a'|| userpick=='A'){
usernumber=2;
cout<<"\nso you picked paper";}
else if(userpick=='s'|| userpick=='S'){
usernumber=3;
cout<<"\nso you picked scissors";}
else{
cout<<"INVALID INPUT,TRY AGAIN!"<<endl;
system("pause");
system("cls");
goto repeat;
}

if(usernumber==number){
cout<<"\nuser picked "<<userpick<<" and the computer picked the same thing, so it is a draw\n";
userscore++;
compscore++;}
else if(usernumber==1 && number==2){
cout<<"\npaper covers rock, you lose\n";
compscore++;}
else if(usernumber==1 && number==3){
cout<<"\nrock beats scissors, you win\n";
userscore++;}
else if(usernumber==2 && number==1){
cout<<"\npaper covers rock, you win\n";
userscore++;}
else if(usernumber==2

Where you want to make loop?
