RSP Game results won't show up

[applj]

I know something's missing but I can't figure it out. it's supposed to be R = 0, P = 1, S = 0 and P2 is a computer opponent that inputs a randomized value. Here's what I've done so far, all I need is to get the result on who wins to show up.

#include <iostream> 
#include <cstdlib>
#include <ctime>
#include <Windows.h>

using namespace std;

class Game
{
private: int rndNum, result;
			char P1, P2, repeat;
			const char R = 'R', S = 'S', P = 'P';
public:  void RSPLogic();
};

void Game::RSPLogic()
{

	do {

		cout << "Input choice of player 1 : ";
		cin >> P1;
		cout << "Input choice of player 2 : ";

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

		if (rndNum == 0) //Computer rock
		{
			result = 0;
			cout << "R\n";
		}

		else if (rndNum == 1) //Computer scissors
		{
			result = 1;
			cout << "P\n";
		}
		else if (rndNum == 2)  // Computer paper
		{
			result = 2;
			cout << "S\n";
		}

		//Player 1 Win
		if ((P1 == 'R' && P2 == 1) || (P1 == 'S' && P2 == 2) || (P1 = 'P' && P2 == 0))
			cout << endl << "Player 1 Wins!" << endl << endl;

		//Player 2 Win
		else if ((P1 == 'R' && P2 == 2) || (P1 == 'S' && P2 == 0) || (P1 == 'P' && P2 == 1))
			cout << endl << "Player 2 Wins!" << endl << endl;

		//Tie
		else if ((P1 == 'R' && P2 == 0) || (P1 == 'S' && P2 == 1) || (P1 == 'P' && P2 == 2))
			cout << endl << " It's a Tie!" << endl << endl;
		cout << endl << "Press [Y/y] to continue." << endl;
		cin >> repeat;
		repeat = toupper(repeat);
	}
		while (repeat == 'Y');
}

int main()
{
	Game obj;
	obj.RSPLogic();
	system("pause");
	return 0;
}

srand() should be called once at the start of the program.

rand() % 3 returns a number in { 0, 1, 2 }. By adding 1, you move the values to { 1, 2, 3 }, but you don't check for those.

You're comparing P1 and P2, but you never set P2. P2's value is in rndNum.

@kbw I totally forgot stdlib.h, my bad. I just replaced 'results' with 'P2' and deleted +1, it's working now thanks for your help!
