assignment help: code gets thrown into infinite loop.

[Brittbritt213]

Im creating a dice game with 2 modes (play with 1 or 2 dice) with 2 human players. When i select 1 dice the program runs as it should, but when i select 2 dice it gets thrown into an infinite loop. Can someone point me in the right direction on where to start?

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

const int PLAYER1 = 0;
const int PLAYER2 = 1;
const int winningScore = 100;
int turn = PLAYER1;


void printIntro()
{
    cout << " Welcome to the dice game: Pig! "<< endl;
    cout << "The goal is to be the first player to reach 100. If playing with one die the rules are that each player can rol as many times as they choose. just dont roll a 1 or else you'll lose your turn AND all points accumulated in that round. If you're  playing with 2 dies the same rules applies, but if you roll snake eyes (double 1's) you'll not only lose your turn but you'll also loose all your points. good luck and may the best player win!"<< endl;
}


int game1(string playerName, int playerScore)
{
    int roll = rand() % 6 + 1;
    cout << playerName << " You rolled: " << roll <<endl;
    
    if(roll == 1)
    {
        cout << " OH NO! You rolled a 1. "<< endl;
        cout << " Your turn is over. " << endl;
        playerScore = 0;

if (roll1 || roll2 == 1) and else if (roll1 && roll2 == 1) are the problem. The || and && cannot join together two objects to test their equality against one. They join together two different boolean expressions so in line 93 the program evaluates roll1 as its own boolean expression. And since the dice can never be zero it immediately evaluates to true so the code will always run as if the players rolled a one; therefore, the program continues to set the score to zero so it needs to switch turns then roll again but since that roll will also evaluate to true this continue to repeats ad infitum.
