Thread: Loops, looping more than they should.

I am working on this program to deal 13 random cards, and for some reason half the time one of my loops is looping more than they should... i cant work out why...

its the do loop in there...

Code:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    start:
    system("cls");
    
    srand ( (unsigned)time ( NULL ) );
    int var[200];
    for (int i = 0; i < 199; i++ )
    var[i] = ( "&#37;d ", rand() % 100 );
    
    
    string getSpade[13] = {"A", "2", "3", "4", "5" ,"6", "7", "8", "9", "10", "J", "Q", "K"};
    random_shuffle(getSpade, getSpade + 13);
    string getHeart[13] = {"A", "2", "3", "4", "5" ,"6", "7", "8", "9", "10", "J", "Q", "K"};
    random_shuffle(getHeart, getHeart + 13);
    string getDiamond[13] = {"A", "2", "3", "4", "5" ,"6", "7", "8", "9", "10", "J", "Q", "K"};
    random_shuffle(getDiamond, getDiamond + 13);
    string getClub[13] = {"A", "2", "3", "4", "5" ,"6", "7", "8", "9", "10", "J", "Q", "K"};
    random_shuffle(getClub, getClub + 13);
    
    
    int nextSpade = 0, nextHeart = 0, nextDiamond = 0, nextClub = 0;
    
    
    string pOneSpade[13], pOneHeart[13], pOneDiamond[13], pOneClub[13];
    
    int f=0,i=0;
    
    do
    {
        if ((var[f]%2 != 0) && (nextSpade <= 12))
        {
            pOneSpade[nextSpade] = getSpade[nextSpade];
            nextSpade++; i++;
        }
        f++;
        if ((var[f]%2 != 0) && (nextHeart <= 12))
        {
             pOneHeart[nextHeart] = getHeart[nextHeart];
             nextHeart++; i++;
        }
        f++;
        if ((var[f]%2 != 0) && (nextDiamond <= 12))
        {
             pOneDiamond[nextDiamond] = getDiamond[nextDiamond];
             nextDiamond++; i++;
        }
        f++;
        if ((var[f]%2 != 0) && (nextClub <= 12))
        {
             pOneClub[nextClub] = getClub[nextClub];
             nextClub++; i++;
        }
        f++;
    } while (i <= 12);
    
    // Print player one's cards.
    cout << "Player One \n"
         << "S: ";
    for (int i = 0; i <= nextSpade-1; i++)
        cout << pOneSpade[i] << " ";
    cout << endl;
    
    cout << "H: ";
    for (int i = 0; i <= nextHeart-1; i++)
        cout << pOneHeart[i] << " ";
    cout << endl;
    
    cout << "D: ";
    for (int i = 0; i <= nextDiamond-1; i++)
        cout << pOneDiamond[i] << " ";
    cout << endl;
    
    cout << "C: ";
    for (int i = 0; i <= nextClub-1; i++)
        cout << pOneClub[i] << " ";
    cout << endl;
    
    // Play again option.
    char ex;  
    cout << "Play again? (y or n)";
    te:
    cin >> ex;
    switch (ex)
    {
           case 'y': goto start; break;
           case 'n': system("cls"); break;
           default: goto te; break;
    }
        return EXIT_SUCCESS;
