dice game of pig

[darkavenger]

Ok I wrote out the whole program and it works except for one problem. Whenever the user or the computer rolls a 1, instead of going to the next player (whether it be from the user to the computer or vice versa) it just lets that same player roll again. I was wondering where my error is?

#include <string> 
#include <iostream>


using namespace std;

int humanTurn(int humanTotalScore);
int computerTurn(int computerTotalScore);

int main()
{
    
    int humanTotalScore;
    int computerTotalScore;
    humanTotalScore=0;
    computerTotalScore=0;
    string playername;
    
    cout << "What is your name?\n";
         cin >> playername;
    cout << "Dice Game of Pig\n";
    getchar ();
    cout << "The goal of Pig is to reach 100 points or more before the other player does.\n";
    cout << "Each time you roll the die points are added to your turn total.";
    cout << "If you roll a 2-6, then you can choose to roll again or stop ";
    cout << "If you stop, then the points are added to your score.\n";
    cout << "But if you roll a 1, then all your points for that turn are lost!\n\n";
    
    do
    {
      humanTotalScore=humanTurn(humanTotalScore);
      computerTotalScore=computerTurn(computerTotalScore);
    
    if (humanTotalScore>=100 && computerTotalScore<=99)
    {
       cout << playername << ", you win!";
    }
    
    if (humanTotalScore<=99 && computerTotalScore>=100)
    {
       cout << "Sorry " << playername << ", you lost.";
    }
    
    else
            continue;
    }
    while (humanTotalScore<=99 && computerTotalScore<=99);{
}

    
    getchar ();
    return 0;
