Making a counter

I'm trying to figure out how to get a counter that will keep score so far everything i've tried wont work. I tried saying that if (outcome = lose) computer + 1 or something like that.. any ideas.

Code:

#include <iostream>
#include <ctime>

using namespace std;

      enum Choice { Rock, Paper, Scissors };
      enum Winner {Computer = 0, User = 0};
      enum Decision { Draw, Win, Lose };
      char DoMenu();
      void CheckWinner(int PlayerChoice);

void Seed()
{ 
 srand(time(0));
}

int GetRandNum(int max)
{
 return rand() % max;
}

int computer = 0, user = 0; 
      int main()
      {     
      
        
       
      Seed();         
               
      cout << "Let's Play Some Rock Paper Scissor!\n" << endl;
      cout << "I Hope to God You Know How!\n" << endl;    
     

      char choice;
      do
      {

      choice = DoMenu();
      switch (choice)
      {

      case 'R': 
      case 'r': cout << "\nPlayer: Rock\n"; CheckWinner(Rock); break;
      case 'P': 
      case 'p': cout << "\nPlayer: Paper\n"; CheckWinner(Paper); break;
      case 'S': 
      case 's': cout << "\nPlayer: Scissors\n"; CheckWinner(Scissors); break;
      default : cout << "\n";
      }
      } while ((choice != 'Q') && (choice != 'q'));

      
  
      return 0;
      }
       char DoMenu()
      {
      char MenuChoice;
     
      cout << "(R)ock\n";
      cout << "(P)aper\n";
      cout << "(S)cissors\n";
      cout << "(Q)uit\n";
      cout << "----------\n";
      cout << "Choice: ";
      cout << "Computer: " << computer << " User: " << user << endl;
      cin >> MenuChoice;


      return MenuChoice;
      }
      
      void CheckWinner(int PlayerChoice)
      {
      int random = 0;     
      random = GetRandNum(3);  
      switch (random)

      {
      case Rock: cout << "Computer: Rock\n"; break;
      case Paper: cout << "Computer: Paper\n"; break;
      case Scissors: cout << "Computer: Scissors\n"; break;

      }

     Decision outcome;
             
      if (PlayerChoice == Rock)
      {
      switch (random)
      {
      case Rock: outcome = Draw; break;
      case Paper: outcome = Lose; break;
      case Scissors: outcome = Win; break;
      }
      }

     if (PlayerChoice == Paper)
      {
      switch (random)
     {
     case Rock: outcome = Win; break;
     case Paper: outcome = Draw; break;
     case Scissors: outcome = Lose; break;

      }
      }
         
      if (PlayerChoice == Scissors)
     {
      switch (random)
      {
      case Rock: outcome = Lose; break;
      case Paper: outcome = Win; break;
      case Scissors: outcome = Draw; break;

      
      }
      }
      


      switch (outcome)
      {
      
      case Win: cout << "You Win!\n\n";break;
      case Lose: cout << "You Lose!\n\n"; break;
      case Draw: cout << "Draw\n\n"; break;
          
      
  system("PAUSE");
  
      }
      }

thanks i tried something exactly like that i did user +1 guess that isn't incremental.. appreciate it.

Your

Code:

/*outcome stores the result 
So at the end of void CheckWinner(int PlayerChoice) function,
check for 
*/
if (outcome == Win)
		  user++;
else if (outcome == Lose)
		  computer++;

No points for tie
